1. Controller connection requirements
Network LAN Connection
Auto-negotiation of a the RaspberryPi 100BT Ethernet connection allows operation of the Controller at the
48000, 96000, and 192Ksps sample rates.
The new piHPSDR-Controller can be connected directly to your ANAN Transceiver and each unit will make use of
the APIPA assignment for an IP address.
CAT-5 or CAT-6 shielded cables are recommended for connection to the LAN
Controller Hardware requirements
13.8vdc 2.5A (minimum 12vdc 2A) Power connection
100BT LAN connection to your Apache Transceiver
Note: when running the dual receiver version of pihpsdr, you may need to place passive
heatsinks on the CPU and LAN chip on the RaspberryPi-3b. Be mindful of the temperature
alarm shown on the right side of the display screen.
Heatsinks like these:

Controller software requirements:
Pihpsdr Controller Operating System and application program are factory installed on an
SDHC card.
If you have purchased the piHPSDR-Controller KIT, you will need to create and install an SDHC card
with the RaspberryPi operating system and pihpsdr application.
Instructions for Installation of Rpi software are detailed in the Install pdf document that is available at:
https://github.com/g0orx/pihpsdr/raw/master/release/documentation/pihpsdr-install.pdf
If you wish to get the latest version of pihpsdr source code, executable binaries, and documentation the
instructions are available at:
https://github.com/g0orx/pihpsdr/raw/master/release/documentation/pihpsdr-build.pdf
Note: it is a good idea to make a backup of your Operating System and piHPSDR software. Use the RaspberryPi
Menu → Accessories → SD Card Copier utility. Use a new SDHC card of the same capacity as the original.
This is easily done using a USB – SDHC card reader/writer dongle plugged into one of the RPi USB ports on the
left side of the piHPSDR Controller.
A pdf document reader is included in the standard RaspberryPi operating system distribution.

5. Quick Start Instructions
please refer to front and back panel illustrations
Hardware Setup
Carefully unpack the piHPSDR Controller.
Connect a CAT 5/6 Ethernet cable between the rear panel LAN jack with proper access to your
Apache Transceiver, Gigabit switch, or suitable router. Please see Network LAN connection page 9.
Connect the supplied piHPSDR Controller power cable to a fused 12vdc typical (13.8vdc) Amateur
Radio station power supply.
Apache Transceiver connections to MIC, KEY, Headphones
Software Setup
The piHPSDR Controller software is pre-formatted on the Operating System SDHC card inserted in
the RaspberryPi.
Alternative software configurations are not provided by Apache Labs.
A person familiar with the Raspbian operating system may wish to modify or update the contents
of the SDHC card using appropriate Linux tools. Please refer to page 10.
Note: pihpsdr is OpenSource. If you would like to compile the program on a Linux system, the
source, binaries, and documentation are located at:
https://github.com/g0orx/pihpsdr/tree/master/release/documentation

6. Discovery Menu
Discover Ethernet Connections to RPi
When first started, piHPSDR will try to discover all the HPSDR compatible radios on the
network. It will look for devices running both protocol 1 and protocol 2 (the new protocol).
If one or more Transceiver interfaces are found they will be identified by the device type,
the software version, the IP address and the MAC address of the device.
If no devices are found you should check connectivity between the radio and the network
that piHPSDR is connected to. Tapping on OK will try discovery again. Tapping on Cancel
will exit piHPSDR back to the Raspberry Pi desktop.
The Discover protocol will allow a device to see and respond even if they are not on the
same subnet. If this is the case, the Start button will be disabled and the text replaced
with Subnet The most common cause of this problem is usually that the radio has not been able to get
a DHCP address and has defaulted to the Self Assigned IP Address, or the device has a static IP address
that is not on the same subnet as the piHPSDR.
11 of 107
pihpsdr v1.2
Pihpsdr program START button
Tapping on the Start button will start the radio – on the selected Ethernet interface.
In this example you see both the Rpi Wireless and Ethernet connections are active and
were discovered properly.
Depending on your particular WLAN and LAN setup, either will work well with pihpsdr
100Mbps network requirement. Both the Rpi and your Apache Transceiver must be on the
same subnet.
Configuration of the GPIO default connections are shown on page 57

Local Audio Output – This column identifies all the audio output connections that pihpsdr recognizes
when it starts.
By default the audio output from the receiver is sent back to the radio for output to the
audio connections on the radio.
You can also output the audio to either the audio output connector on the Raspberry Pi or a
USB connected audio device.
To enable output to a selected device check the Local Audio Output check box. The output
will be directed to the selected device.
plughw:0,0 bcm2835 ALSA is the Raspberry Pi output to the audio connector.
plughw:0,1 bcm2835 ALSA is the Raspberry Pi output to the HDMI interface.
plughw:1.0 USB Audio CODEC is a USB connected audio device.
Only one output stream can be directed to the devices listed above, but the ALSA sound
system includes a mixer that lets multiple streams output to a single device.
dmix:CARD=ALSA,DEV=0 is a mixer for the plughw:0,0 bcm2835 ALSA output
dmix:CARD=ALSA,DEV=1 is a mixer for the plughw:0,1 bcm2835 ALSA output
dmix:CARD=CODEC,DEV=0 is a mixer for the plughw:1.0 USB Audio CODEC output
Stereo, Left, Right, Mute when not active
If you select the same dmix device for both receivers, the output from both will be mixed
and sent to that device. You can select that the receivers output is either Stereo, Left or
Right to select the channel(s) that the audio is sent on. This would allow one receiver inn
the Left headphone/speaker and the other receiver in the Right headphone/speaker.

pihpsdr v1.2
The Mute when not active when selected will simulate the output to the radio where only the
active receiver is output to the device.
Note that if one receiver’s audio is set to output to the plughw device the other receiver cannot be
connected to the dmix device for that audio output.

Menu → FreeDV
FreeDV: Open Source Amateur Digital Voice by The FreeDV.org. piHPSDR uses the FreeDV API.
FreeDV provides a number of codecs that can run on HF over a typical SSB channel (1600, 700,
700B, 700C an 800XA). It also includes codec for running over FM channels on VHF/UHF (2400A
and 2400B).
Speech is compressed down to 700-1600 bit/s then modulated onto a 1.25 kHz wide signal
comprised of 16 QPSK carriers. FreeDV 700C is approaching SSB in it’s low SNR performance. At
high SNRs FreeDV 1600 sounds like FM, with no annoying analog HF radio noise.
Enable FreeDV - when enabled microphone input is passed to the FreeDV library for encoding and
the output is passed into WDSP for processing into I/Q signals for transmitting. On receive the
audio output from WDSP if passed to the FreeDV library to decode the audio.
SNR Squelch Enable - when enabled uses the SNR value to set the squelch. SNR shown in RED
letters next to S-Meter. Adjust as needed to achieve quiet idle.

explanation of “Low Latency” buffer optional
June 10, 2016 - Warren, NR0V and Doug, W5WC
PowerSDR/OpenHPSDR_mRX_PS v3.4.2 has been released.
This release can be downloaded from the OpenHPSDR.org git repository.
This release contains the following changes:
SIGNIFICANTLY LOWER LATENCY
Receive latency is the time between when RF reaches your antenna and the corresponding
audio is produced in your speaker or headphones. Similarly, transmit latency is, for
example, the time between audio reaching
your microphone and RF being on its way to your antenna. For many SDRs, especially those
with sharp "brick wall" filters, the latency can be much larger than you might expect.
Depending upon the radio design and various settings, SDR latencies can significantly
exceed 100mS. Long latencies can create problems for the operator in contest operation,
high-speed break-in CW, and even SSB rapid-turnaround VOX operation.
This release incorporates some technologies that allow us to achieve low latencies in the
same category as leading conventional radios. Furthermore, we can do this with extremely
sharp filters.
First of all, a couple basics:
* Sometime ago, we moved CW Transmit from software to the FPGA in the radio hardware.
This means that CW transmit latency was already very low, really based upon your delay
settings which are chosen to avoid any hot-switching of relays.
* It has always been the case that the Buffer Size setting on the Setup=>Audio/Primary
tab effects latency. The lower the size, the lower the latency. However, the lower the size,
the more CPU cycles are required. Depending upon the speed of your computer, you may be
limited in how low you can go. Fortunately, this is not likely to have such a large impact on
your latency. For a very rough estimate of the latency due to this buffer, divide the buffer
size by the sample rate. For example, a buffer of size 256, at a sample rate of 192K,
contributes only about 256/192000 = 1.33mS.
69 of 107
pihpsdr v1.2
As of this release, there are some new features and corresponding controls to allow you to
achieve much lower latency:
* Up until this release, "Filter Size" and "DSP Buffer Size" have been the same and there
has only been one setting, called "DSP Buffer Size." Filter Size determines how sharp your
filters are; higher filter size leads to sharper filters. However, higher DSP Buffer Size leads
to more latency because we must collect enough samples to fill the buffer before the buffer
can be processed. As of this release, DSP Buffer Size and Filter Size are separate and can
be set by mode on the Setup=>DSP/Options tab. So, using a very low DSP Buffer size
minimizes latency and using a high Filter Size leads to sharper filters. The trade-off here is
that using lower DSP buffer sizes requires somewhat more CPU cycles and using a high
Filter Size does as well. With a reasonably fast computer, you will likely be able to run at a
DSP Buffer Size of 64, the minimum, except, perhaps, for the FM mode. With filter sizes of
1024 or 2048, the sharpness of our filters rival the best radios. However, larger sizes, up to
16384, are available if you need them.
* You now have a choice of Filter Type, with two types available: Linear Phase and Low
Latency. In the past, our filters have always been Linear Phase. Linear Phase filters have
the property that all frequencies are delayed by the same amount of time as the signal is
processed through the filter. This means that the time-domain waveform of a signal that is
totally within the passband will look the same at the input of the filter and the output of the
filter. The Low Latency filter does not strictly comply with this same type of operation.
With the Low Latency filter, signals at frequencies very near the lower and upper edges of
the passband may experience more delay than signals at other frequencies. Comparing the
two types of filters, beta testers have reported little, if any, difference in sound quality, no
problems with several digital modes that have been tested, and no significant negative
impacts at all from using the Low Latency filters. However, both filter types are provided
for your comparison and your choice. Of course, the Low Latency filters provide lower
latency. In fact, the latency of Linear Phase filters increases linearly with Filter Size while
the latency of the Low Latency filters is very low and nearly independent of Filter Size.
Benchmark Comparisons:
* For CW/SSB receive, using minimum Buffer Sizes and Low Latency filters, our beta testers
have measured receive latencies in the 15mS to 20mS range. Using minimum Buffer Sizes
and Linear Phase filters, the latencies are 25mS to 30mS for a Filter Size of 1024 and 35mS
to 40mS for a Filter Size of 2048. Using features such as noise blankers, EQ, and noise
reduction will add some amount to that, depending upon the feature(s) and settings. These
numbers compare with ~65mS and ~120mS using DSP Buffer sizes of 1024 and 2048,
respectively, in prior software releases.
NOTE
You WILL need to reset your database. This release will build a new wisdom file on first
time use. Depending on your system, it may take a very long time to complete. Please be
patient.
Thanks & 73,
Warren, NR0V

pihpsdr v1.2
15. Steve Wilson KA6S special addition for Fldigi
Using PiHPSDR with other applications:
PiHPSDR emulates several commands available in the CAT control found in the TS-2000.
However, it receives commands over TCP/IP instead of through an RS-232 connection. For
some applications this is trivial – for others some internet plumbing is required.
The Basics
PiHPSDR listens on Port 19090 for TCP/IP connections. It interprets TS-2000 protocol
commands and will respond appropriately. It is NOT a full implementation. Some things
don't make sense, i.e. they are features not shared between the TS-2000 and PiHPSDR.
Others are still to be implemented.
Note: The latest version of Hamlib has a radio definition for the PiHPSDR, thus any application that
uses Hamlib will be able to talk to PiHPSDR in its native manner, i.e. directly through TCP/IP without
using the serial port. (Thanks to Jae, K5JAE for the hamlib port!) The serial port methodology is
presented here for older iterations of Hamlib. To get access to to native support you will need to
compile Hamlib from source and install it. That is beyond the scope of this manual.
Note that before you can begin using this connection you must configure and enable it through the
main menu. This is done by choosing RIGCTL from the Main Menu:
71 of 107
pihpsdr v1.2
Raspberry PI
Linux/Windows
Application
Use the Raspberry PI
TCP/IP Address
And set for Port 19090
Ethernet
PiHPSDR
Upon hitting the RIGCTL button the configuration menu is presented.
By hitting the Rigctl Enable Button you can turn on the CAT control system. Hit Close to continue.
Note that if you exit the program at this point RIGCTL will remain enabled. It is also possible to
change the default Port number by using the -/+ buttons to decrement/increment the port number.
ping a Serial Port to TCP/IP port in Linux
Perhaps the easiest way to do this is via the utility “socat” available in most Linux distributions. This
72 of 107
pihpsdr v1.2
utility is sort of a swiss army knife for interconnectivity, and one its abilities is to map Linux Serial
ports to TCP/IP ports.
To obtain “socat” and install it on an Ubuntu system type:
sudo apt-get install socat
To use it – first start PiPHSDR. You need to know the TCP/IP address of your Raspberry Pi. This will
be a 32 bit number formatted as XX.XX.XX.XX. I'll use 192.168.1.73 in some examples,
192.168.1.76 in other examples. These are where I have HPSDR radios assigned in my local network.
To run it – type:
socat pty,link=/tmp/vtty,raw tcp:192.168.1.73:19090&
This will do two things. It creates a fake serial port called /tmp/vtty that can be opened by most
applications and acts just like a serial port.
The next step is to point your application at /tmp/vtty where you would normally choose a serial port
and set it to talk to a TS-2000. It really is that simple!
This allows applications that are built to use Hamlib to talk to PiHPSDR.
Example: Set up GRIG to talk to PiHPSDR
grig –-model=214 –-rig-file=/tmp/vtty *
/tmp/vtty is a temporary file – it disappears as soon as socat ends.
Grig is built around the Hamlib radio access library. The TS-2000 is model 214 in Hamlib. Any
application that uses Hamlib should be able to communicate with PiHPSDR by using /dev/vtty and
choosing model 214 as the radio.
Something else to realize is that more than one application can talk to PIHPSDR at a time. PiHPSDR
supports multiple connections to the CAT port.
If you have the latest version of Hamlib that supports PiHPSDR natively – the command to start grig
73 of 107
pihpsdr v1.2
would be:
grig –model=240 –rig-file=192.168.1.73:19090 &
Example: Connect FLDIGI to PiHPSDR
FLDIGI can be connected to PiHPSDR using the native PiHPSDR interface built into the latest version
of Hamlib. However, it polls PiHPSDR way to fast.
Have no fear – FLRIG is here. FLRIG is a companion application to FLDIGI that can act as a server
for FLDIGI.
You can install FLRIG on with:
sudo apt-get install flrig
You can install FLDIGI with:
sudo apt-get install fldigi
Start FLRIG first with
flrig
No need to start it with sudo since it talks directly to PiHPSDR.
To set up FLRIG – Hit the Config button on the top of the application and Choose
Config/Setup/Transceiver – the Window below will pop up.
74 of 107
pihpsdr v1.2
Use the arrow to the right of the Rig: box and slide it to TS-2000.
Also – check the PTT via CAT button in the lower left corner.
Hit Close
Now Choose Config/Setup/TCPIP
The window below will pop up.
Select the TCPIP tab. Enter the TCPIP address of your Raspberry Pi – in our example you see
192.168.1.73. Type in the TCPIP box 19090 and that should do it. Hit the “Use tcpip” button. If the
connected light isn't green – hit the Init button in the upper right portion of the window.
Hit Close and you should have FLRIG up and controlling your PiHPSDR.
75 of 107
pihpsdr v1.2
The Frequency should work by using the scroll wheel over the digit you want to change.
The volume, RF, PWR, and MIC sliders should all work.
The PTT should cause the radio to transmit.
The S Meter should register.
Now get FLDIGI running.
Type:
fldigi
Choose Configure/Rig Control
Hit the flrig tab and the window below will pop up.
Hit the “Enable flrig xcvr control with fldigi as client” button.
Note that the TCP/IP address is 127.0.0.1 – which is the same as the machine you are running flrig and
fldigi on. The TCP/IP port 12345 should already be configured.
Also hit the “Flrig PTT keys modem”
That is it.
76 of 107
pihpsdr v1.2
You need to use actual audio cables from the Radio to your Linux computer for the audio as of now –
but this should be all that is necessary for FLDIGI to talk to your radio!
Setting up rigctld
The Hamlib system must be installed to use some packages – specifically to run the rigctld daemon.
On Ubuntu:
sudo apt-get install libhamlib-utils
sudo apt-get install libhamlib2
Note: These packages don't yet have PiHPSDR supported natively. It is necessary to compile the latest
version from source and that is beyond the scope of this manual.
Multi-Client Support
PiHPSDR can communicate with multiple independent clients simultaneously. An example
of this might be running FLRIG/FLDIGI with the logging program CQLOG.
First – make sure you have CQLOG installed.
On Ubuntu:
sudo apt-get install CQLOG
We need do three things to get cqrlog running.
1) Create a virtual terminal – see the instructions above about running cqrlog. There is one change here.
We're going to aim the virtual serial port /tmp/vtty at TCP/IP port 19090 again.
2) Start up the hamlib rigctld – this is a “daemon” in Unix parlance that is responsible for interfacing
between applications and the virtual terminal using the internal hamlib protocol. Note that SOME
applications have the hamlib software built in, while others use the daemon – cqrlog uses the daemon.
The rigctld must be started using “sudo”
3) Start up cqrlog. Specifically do NOT use “sudo” for this command.
In a single xterm – you can start up both socat AND the rigctld daemon. Note again the use of “sudo”
prior to the command AND note that the first program can be put into the background safely. Rigctld
doesn't work if you do that..
77 of 107
pihpsdr v1.2
In another xterm – start up cqrlog
Enter: cqrlog &
This will start up cqrlog talking the PiHPSDR radio using port 19091. Note that this can be safely put
into the background using the ampersand operator.
Configure cqrlog as shown in the picture below:
Note that we are choosing to NOT launch rigctld when the program starts – but rather starting it by
hand.
Next – start up flrig as you have previously using port 19090. It should be configured correctly from
the first time you used it. Since cqrlog spouts messages – you may need to use another xterm…
% flrig &
And this you can start up FLDIGI using the same xterm..
%fldigi
The picture below shows all applications running – using the two TCP/IP ports.
78 of 107
pihpsdr v1.2
Running applications with the latest version of Hamlib
The biggest advantage of running applications through latest version of Hamlib is that the whole virtual
terminal concept is removed! Applications can talk directly to PiHPSDR without any middleware. I'll
use CQRLOG to illustrate the setup.
The first trick is to make rigctld runnable without being root. THIS IS A SECURITY HOLE – Proceed
at your own risk! The following command allows rigctld to be run without being root…
sudo chown pi /usr/local/bin/rigctld
This makes the user “pi” owner of the rigctld daemon.
Next – start up cqrlog and set up its preferences as shown in the next picture.
79 of 107
pihpsdr v1.2
Things to note:
Rig Model is OpenHPSDR PiHPSDR – radio model 240.
Device: Use the TCP/IP/Port number – so 192.168.1.73:19090
The “Run rigctld when program starts” is checked – since we don't have to root to run rigctld.
It is also possible to start cqrlog on OTHER than the Raspberry Pi. The settings would be the SAME
since the device entry is what actually aims the communications at the PiHPSDR TCP/IP port. Rigctld
can be started on another machine and it will be able to communicate via TCP/IP directly to the
PiHPSDR application.
Using CAT through a Serial Port
The latest update to PiHPSDR can also operate over a USB Serial port. This will allow normal
connection from a PC to PiHPSDR through a serial port similar to other radio CAT connections. Note
that multiple connections are concurrently available through the TCP/IP connection as previously
described after the Rigctl Enable button is lit. These two paths function independently.
It is important to set up the Baud Rate and choose the USB port BEFORE you enable the Serial Port!
It is also important to plug in the USB to Serial adapter before you try and enable the function. Note
that the Serial Port Enable will NOT stay lit if there is no /dev/ttyUSBx port available.

pihpsdr v1.2
Configure the Baud Rate by selecting one of the 4 choices shown below:
Use the +/- buttons to change the USB serial port to match what is available on your system.
Once the Baud rate and /dev/ttyUSBx port are selected – enable the Serial Port by hitting the Serial
Port Enable Button.
If the Serial Port Enable button doesn’t stay lit – no /dev/ttyUSBx was found.

KA6S Summary
PiHPSDR provides a TCP/IP channel on ports19090 which can communicate with other applications
using an emulation of the TS-2000 command set. The port number CAN be configured on the
RIGCTL menu, as well as enabled/disabled.
Some applications require a virtual serial port – use the socat command run to create the virtual serial
port.
The very latest version of Hamlib supports PiHPSDR natively. Radio model is 240, and uses TCPIP
Address/Port Number instead of the serial port.
Other applications require the hamlib rigctld to be present – start /usr/bin/rigctld with sudo.
To run FLDIGI – use FLRIG as the server for FLDIGI since FLDIGI has issues talking to the virtual
serial port.
Conventional connection to PiHPSDR is available through a USB to Serial adapter plugged into the
Raspberry PI by enabling the Serial Port Enable button.
