ugh...that's as bad as the guy that used to use phonetics...he got banned from just about every repeater and club in nearly 100 miles...I'm sure he got in trouble with 'the man' too...interfering with emergency nets in progress was a big one too.

I'm trying to figure out why our mtr2000 isn't passing any audio. We're using an external repeater controller through the wireline connector. This is new to us, and we're trying to get things set up before we go to the site.
Before I try too hard and break something...
Is that 4 pin connector (J6) supposed to come off?
How do I release the wires? I tried pushing into one of the small holes, figuring that would release a clamp. The wires aren't budging.
Thanks. Don

Re: 220Mhz ACSB amplifier

Re: Attempting to program a Maxon SM2150. Looking for proper prog cable. Have software.
Thanks Max.
Too involved for me. I thought I could find am SMP2000 prog. cable and program thru the mike jack. (I have no info on the D shell 15 pin connector on rear of radio above power cable. inlet. No info at all on the 15 pin connector.
I'm going to look for some Icom F-121 radios and shelve the Maxon SM-2150's.

Checkout the files section.? Note: none of this is verified and YMMV,? I don't have this radio! Just interest in such things and late night technical ramblings.?
A check of the Service manual SM-2000 and it appears when the CPU puts the radio in programming mode (as per the programming manual) it switches over three lines IC412 4053.
DO, DI and SK from their normal functions on the 6pin RJ MIC connector , PTT, Mic and Hanger.? CS is also needed for 93C46 EEProm is present on the Mic connector.?
Tried the software SMP4004C in Dosbox-x and boy I miss the simple DOS programs, that actually work in a small amount of code.?
Just don't know how they generate the SK = serial clock pulses. The SMP2000 cable looks like a 9pin D to the 6 pin mic plug. Maybe worth a CRO look at the pins when trying to program to determine if there is a clock pulse there somewhere! CCT also shows an 8 pin socket inside the radio with same programing pins.?
?
Otherwise?
Then as a last resort I found page to directly read the EEProm and be able to write data from the software back into it. Again all care and no responsibility!??
might be useful information too.?

Re: MTR2000 channel steering
I've never done it with the MTR 2000 but I suspect it would be channel steering using the GPIOs via wildcard programming.. I've only stuck an MTR 2000 on only one frequency ?
I'm trying to figure this out. The Moto lit says up to 32 channels and the Wildcard tables show the 96-pin connector GPIOs, but... I don't understand the programming UI. First, is binary channel steering possible without optional cards? Second, does anyone
have any explanation of how to do this, perhaps with screenshots? Yes, I can jig up a radio and play, but I'd prefer not to reinvent fire.

That doesn't sound right: I remember reading through some old CoFeTel
(former Mexican FCC) documents & seeing all the amateur repeater
pairs available in Mexico.? There definitely were 220 MHz amateur
pairs in those documents, so it sounds like a local Mexican official
decided to just do whatever he wanted, in violation of their own

Re: Attempting to program a Maxon SM2150. Looking for proper prog cable. Have software.
It may be worth a look to the SPC-4000 or SM-4000 cable.?
I have a similar GE version of this radio, sm-4150.?
Radio is programmed with a serial cable connecting to a six pin connector on the radios board, revealed by taking off the covers.
Attempting to program a Maxon SM2150. I have software but having a tough time locating a programming cable.
The information I find tells me the SM 2000 series requires Maxon SMP 2000 programming cable.
I'm prepared to purchase a cable (or borrow).
It is my understanding that the prog. cable plugs into the mike socket (RJ). My SM 2150 has a 15 pin connector directly above the +12 VDC wires. Would this be a prog. connection? I have no info on this connector. Having the rear connector confuses things.
I'm not certain whether the radio programs thru the mic. connector or the rear connector. If the rear connector is for programming, then the SMP2000 would be an incorrect cable.
Hopefully someone will have an answer.

Re: 220Mhz ACSB amplifier
All 220 Linear amps should work great on 220 FM without any mods except maybe the addition of a small fan but even the fan isn't really required.
?
?I had several Morrow electronics/UPS Aviation Technology/Garmin Aviation Technology 50 watt 220 MHz Linear amps from the days when they stole the lower half of the 220 ham band and they all work just fine on 220 FM for my remote base and as mobile amps without any mods at all.
?
I added a small fan but even without the fan I haven't killed any yet but for me it was a psychological thing just knowing that the transistor junction temp was always going to be below the data book max.? even if stuck in tx for an hour.
?
My amps are all around 50 watts out each and with a home brew wilkinson? combiner I have? around 90 watts going to the antenna.
