Re: MT-1000 - modifying for reception
|
Rob,
The MT-1000 is a transmitter-only, but it has a transceiver module in it. The RX is kept off to save battery power, since holding off transmissions based on a busy channel is a non-starter for a transmitter that is designed for high altitude operations. The same unit product, less the APRS specific stuff ( GPS, temperature sensor, etc) is also used for our MF-PC Fox hunt transceiver, which may be programmed and remotely controlled via DTMF tones. The same RF module is also used in the MTT4B's ( On production hold currently) and the DTMF receiver decoder called the DTMF Remote (). The DTMF remote is what I would usually recommend for? controlling an HAB, since you can control determine the control frequencies for command controls and ACK's as well as CTCSS and DCS, so there is little chance anyone will cut down your payload with an "accidental" APRS command. ( Its much more fun to take down HAB's with 2 Million dollar missiles)?

I am pretty sure All the MicroTrak products are TX only.? So the MT8k is a transmitter - not transceiver. You would need an MTT4B to get a transceiver.

Hello,
I have an MT-1000 which I'm planning to use on a high altitude balloon. I was wondering if it was possible to configure it to keep the transceiver on at all times. That way, I can tap the audio from the unit and run it through a demodulator, so that I can use APRS packets to control the balloon from the ground.
I would use a second transceiver for reception only, but I'm worried about blowing its frontend with it so close to the MT-1000.
Thanks!
