Specifications
I. Introduction:
The MK9A transmitter is a portable, low power, single-frequency, pulsed transmitter designed for rugged
service in a variety of environmental conditions. The transmitter and a 3.6V lithium battery are housed in a
hermetically canister, with a mounting tab for convenient mounting. The 18” long permanently attached
antenna is made of flexible, Teflon [PTFE] coated wire. The MK9A emits a train of unmodulated RF
pulses, with pulse width, pulse period, and frequency factory configurable. For operation under MURS
rules, the transmitter may be factory programmed to any of the following frequencies (151.820, 151.880,
151.940, 154.570, and 154.600MHz).
II. Operation:
Antenna –
The MK9A antenna is constructed of PTFE coated multi-strand stainless steel cable and is designed for
easy deployment in a variety of configurations. Note that best radiated power will be obtained when the
antenna is deployed in open air, away from conductive objects. The antenna can be coiled, placed near
conductive objects, or otherwise compacted without damage to the unit. However, the effective range of the
transmitter may be reduced as a result.
On-Off Function –
The only user-controlled feature of the MK9A is the on-off function. Placing a magnet over the arrow
marker on the package (see fig 1a) causes the transmitter to shut down. Removing the magnet initiates the
transmitter. Note that the transmitter indicates a clean restart by sending a series of 5 pulses in rapid
succession when the magnet is removed.
Programming and Initialization –
The following parameters of the MK9A are factory configurable:
- Frequency (select from any of the 5 MURS frequencies)
- RF Pulse Width (15-250msec) 20msec standard
- Pulse Period (400-2000msec) 800msec standard
MaintenanceSince the MK9A is sealed in a hermetic package, it is not user serviceable. Contact the factory for
reprogramming or battery replacement.
