I seem to recall that if it was ever associated with MDC 1200 or some other data device there is a lead somewhere on the plug that can disable the PL transmit during data transmissions. Hope that

Found the instructions here: https://www.repeater-builder.com/motorola/mtr2k/pdf/celwave-pd526-4-2-uhf-duplexer.pdf Instructions used an RF millivolt meter for some of the adjustments but I used an HP

One version of the factory tuning instructions says to remove all cables, tune each pass/notch separately, attach all cables and put into service. I was skeptical but tried this and it resulted in a

Check out the west mountain radio Epic powergate. It will charge all battery chemistries and switch from power supply to battery power in

Are you tuning each cavity separately for both pass and notch, then connecting first two together and then the third for each side. The connecting cables should be 11.5 inch, face to face, then look

I'm still looking to trade an ics quantar controller for a northcomm quantar controller. I'm not sure but it seems I might have been ghosted by the last person i was talking to about a swap. If there

I have an issue with tuning a duplexer. As you can see from the pictures the high pass looks good but the low pass has a double peak. I am having an issue trying to merge that double peak into one

I second and third Jeff and Tom's recommendations of battery-specific chargers.? Then deep-cycle AGMs vs liquid electrolyte car/marine/RV batteries. I'm building battery backup packages for a couple

I can't speak to the 1U units.??? The units I'm familiar with were 2? or 3 RU, and the modules were vertically oriented. Looks like I downloaded the spec sheet in 2015, and I think we bought it

It is transmitting just as it should. Voltages are where they should be on the encode board. I have not looked at it through a scope yet. That will be something I look at tomorrow. I tried a few

* drives the varactors in the channel elements with the composite voice and PL tone. Sorry, brain fart, I forgot that we were talking about a UHF Micor mobile rather than a repeater. There is still

I'm more confused after reading your second post. The link you provide below is to modify a Micor PL encoder so that it doesn't send reverse burst. It doesn't cover what is required to install a PL

Okay... Please answer the other questions. Additionally - does the transmitter key properly with the encode board installed? Kevin

Kevin, Sorry for the confusion. This is referring to the encoding of pl. nothing to do with decode. The decode portion of the radio works great...sorry for the confusion. Here is the

Tyler, You seem to be saying that you installed a decode board, but it doesn't encode.? You do realize that decode and encode on a MICOR mobile requires two vastly different boards?? If you

I have a low uhf micor mobile (old board) according to the manual. it did not have a decode board in it when I got it. i put one in it and did the mod to the board to bot key the exciter at all times.

Greetings, I'm looking for a copy of the NU-140 power supply. This is the 110 AC supply used on the P series 5 Watt high band (10 Watt low band) P33 Handie Talkie. I have the schematic of the later

Look into Victron Energy Smart Battery Protect 12/24v. They have models rated at 60 to 200+ amps and are bluetooth app. programmable. A 100A cutout costs roughly $75 usd. They make diode isolators,

Use an external "smart" battery charger compatible with your chosen battery capacity and chemistry, a diode block (aka battery isolator), and a low-voltage disconnect. I would not suggest spending

Would like to add the battery backup option to an existing Astron RM-50M. Interested in suggestions on the best way to accomplish this. 73 Martin W2RWJ
