Re: Motorla INTRAC (SCADA) stuff anyone?

would you need that to just decode?

I would like to just use the boxes to receive telemetry from multiple repeater sites/voters etc...

I have tons of them so would love to do something besides strip them for LEDs and voltage regulators

but I have a feeling like that won't be possible :(

Don't take my post as being discouraging, it was meant more that when it comes to the science of doing it, you need to read very carefully, since simulcast is all about timing. You will need high stability oscillators in order to make the system work, that I know, since timing is tight. There are a...

My two bits worth: The M-ll PA is not noted for reliability. Yes, you can turn the power up, but at what cost for a db or so? The system effects of output power is so overrated! you can lose 3 db (1/2 power) and never notice it. A 4 section Pass/Reject duplexer should do the job. The choice of ante...

There's no chance in hell of ever converting an HT750 to an HT1550 Also, it's a firmware mod, not a VCO Mod... you're not going to be able to change bandsplits, I don't know why people think that they can do that... if that's the case, perhaps you shouldn't even consider hacking because then we'll ...

would that same trick work to upgrade the HT750 to a 1250/1550? I have a few of those too...

also would flashing a low uhf radio into a high uhf radio change the bandsplit?

That's a nice way to make lots o' watts, but it doesn't keep the Maxtrac from shutting down when it thinks it must be too hot. ah so the radio just thinks its getting too hot... hrmm, i wonder how effective it would be to just make a circuit to unkey the radio for 1/100th of second every min or if ...

OR

you could just disconnect the PA on the maxtrac and run the 10mW exciter power into something like a MASTR III PA that uses a 10mW drive anyway for 110w out, and that is rated for continious duty
