Hi All,

I've got a UHF desktrac repeater that for some reason will not break squelch on my mobiles. I've checked it on the RSS and the TX/RX frequencies are correct as well as the PL codes. My mobiles and handhelds will only receive the signal from the repeater if I have them set for carrier squelch. When I have them set for the same PL code as the repeater, they can't hear it. I've been through the radios and the repeater, and all looks well. Anyone have any ideas? Thanks in advance.

You might want to do a search on the PL issue
here. Remember something some time back
about the way the radio was programmed. Can't
think what the cause was at this time.

Are you using 1225 series radios? if so are you using dpl 023?

Check the ACCY pin outs for PL/DPL STRIP or something to the same end on the DeskTrac TX radio. Reprogram that to NULL.

When using a local mic to TX on the DeskTrac, does it send the PL?

Hi All,

First... thanks for the responses. All help is appreciated.

Here's the model #'s of the TX/RX radios as read by the cpu.

TX #D44MJA7DA5_K

RX Same as above.

If memory serves me, these are Maxtracs.

Will, there's nothing in the RSS that shows ACC pin outs, unless they are external or I need to read the radio with Maxtrac RSS. The desktrac software has limited options. I did read it first with the Maxtrac Rss but didn't save it to the drive because it stated that I couldn't save it back to desktrac.

I haven't tried it with a local mic, but I can do that tonight to see if that works. I'm not the worlds best at this, but it has me stumped.

Thanks again,

Bundy

Will,

I tried your suggestion of keying through the local mic and it didn't break the squelch on a hand held. This is puzzling. Could it be a duplexer problem?


Thanx,

Bundy

Are you sure the repeater is transmitting PL?
Are you sure the desktrac is keying the repeater up?

I'm not too sure that the repeater is transmitting the CTSS but it does key up both locally and remotely by handheld. The PL codes for both tx and rx are 5Z as depicted in the rss, but when you put one HT that is programmed with the same CTSS (tx/rx) and the other with 5Z tx and carrier squelch the repeater will not break the squelch on the one with PL, and can be heard on the other. The repeater pretty much works like it should as long as the HTs are programmed to receive by carrier squelch. It wouldn't be so much of a problem except the amount of skip we get from a city north of us.

You will need to 'read' the TX radio with the MaxTrac RSS.

Set up the Desktrac RSS, read the TX radio to be sure that the switch is in the correct position for the MAIN/TX radio.

Then use the Maxtrac RSS with the same cable/RIB combination from the DT RSS. Read the TX radio and double check the settings.

Thanks Will. I'll do that and let ya know what I find.

Bundy, When I get back I will look up another item that may be a problem in some applications and let you know how to check for that.

That would be very much appreciated Will. Be safe.

PS: A very big thanx to all who have replied. The folks on this board continue to make it great.
