Continuous TX'ing

captainkirksdog · Post by **captainkirksdog** » Fri Dec 21, 2001 3:19 pm

Does anyone know the FCC rules on continuous transmitting on, say, an MT1000, on an unused channel? Also, can this radio handle it? It won't hurt the final RF out amp, will it? I would like to use this radio for remote telemetry. Any input is appreciated. *CKD*.

Hello captainkirksdog! It will burn out the final! (or hurt it, even at mw for extended tx) I'm sure the http://www.arrl.org/ has a bunch of telemetry items you can build! As for the FCC. they have band allocations for becons or telemetry....But whats the bottom line if your on an unused freq. with/without license/permission...$10,000. fine ..If your not interfearing with another agency? Since the fcc is kinda broke right now! you can bet a heavy fine or worse.

Hey , be sure to check around on ebay, I've seen low power Motorola telemetry transmitters from time to time on ebay.

The most recent was a lot of them that came from a forestry service somewhere, they used them to get measurements from rivers.

Check around on ebay, you may find a great deal on one!

Duty cycle on the Mt1000
is 20% Telemetry we use it with
ht600 vhf 5 watt and on propane power.
Works great. We have the transmitter
turn on each 15 min's for 45 sec's.
Been running 3.2 years.zero trouble.

Just got a flyer from MDM in Chicago two days ago that lists Motorola P-10 1 W xtal controlled 450-470 Mhz data xcvrs, 2 freq capable, 7.5 VDC, for 25.00 each. That help you any?

Hi:

Motorola did make some low cost telemetry
Systems.

One was made from a HT90 Tx Board, and even
had a Receiver Board to so they could be used
as a small low power repeater.

I have a few of them if you are interested.

I also have some real neat low power UHF
Transmitters which run off 12VDC, use Maxar
Style Xtals, and they transmitt about 1/2 to
1 watt, and are designed for continious duty

These are not Motorola, but were built
for a Remote UHF Alarm Notification system

Would be will to do some trading if you are
interested
