Hi All,

Is there anyone in the Phoenix, Az. area that can program an XPR series radio for amateur use to use the DMR-MARC net? Anyone I have contacted so far say they work for Moto and cannot do it.

BTW- I emailed both Moto Comm companies in the valley with no response.

I am quite hyped about this radio and it's capabilities. Wanting to try it for myself. Any help would be greatly apreciated.

Yes, well the version 3.0 board has very good voltage protection - both
reverse diode, transorb, and resettable current limiter (fuse). I have heard
of the old 18-pin "through hole" DTMF chips that sat in the chip socket
going bad from static discharge and voltage spikes. I saw that two of the
posters on the forum had mentioned that they were the older version 2.0x
boards, which has no voltage protection.

That surface mount chip will be near impossible to get off of the board
without heating the whole board up and lifting the chip, which requires
special equipment. I use faulty boards from the manufacturer for spare parts
for repairing boards, and I have yet to get one of those chips off without
damaging either a lead on the chip or a trace on the board.

Again, I would caution you to check the crystal first.

Do all of the functions on the board work (all LEDs, COS circuit, PTT
circuits)?

Check that the audio from Pin 8 is also present on both sides of C5, and
both sides of R6.

Check the solder connections on Y1.

Verify there is +5 volts on pin 18 (top left pin on chip when reading the
letters on the chip the correct way).

I personally have never seen a failed DTMF chip on these boards, and being
the person that built all of them, I am surprised I have not heard of any
failures of the DTMF chip before today. There are over 5000 version 3.0

Re: Board no longer sees DTMF

Yes, well the version 3.0 board has very good voltage protection - both reverse diode, transorb, and resettable current limiter (fuse). I have heard of the old 18-pin "through hole" DTMF chips that sat in the chip socket going bad from static discharge and voltage spikes. I saw that two of the posters on the forum had mentioned that they were the older version 2.0x boards, which has no voltage protection.

That surface mount chip will be near impossible to get off of the board without heating the whole board up and lifting the chip, which requires special equipment. I use faulty boards from the manufacturer for spare parts for repairing boards, and I have yet to get one of those chips off without damaging either a lead on the chip or a trace on the board.

Again, I would caution you to check the crystal first.

Do all of the functions on the board work (all LEDs, COS circuit, PTT circuits)?

Dave,

Three people have so far written me to say that they have had to replace that chip, so it does appear to be a real problem. I will go ahead and have it swapped out to see if the problem is solved. If not, I may need to get back to you ;-)

Note that "something" killed multiple items on my system while I was away: 19v power supply, voltage conversion board in ITX case, ITX motherboard. Whatever did this damage very likely could have zapped this chip, so I wouldn't really consider the chip "bad" from that standpoint.

Re: Board no longer sees DTMF

Mitch Wolfson
 

Thanks for the offer, Tony, I appreciate it.

Since the node otherwise works, except for DTMF, I will not take a look the board again until I have the replacement chip in a couple of days. Maybe I am lucky and it is socketed. Otherwise, I may get back to you if I don't hear back from some local inquiries here in Munich for SMD soldering talent.

Re: repeater deviation

Dave K9DC
 

I guess the short answer to your question is yes.

But setting up the audio is not quite so simple. First the repeater transmitter needs to set to proper deviation by itself. Mine are set to 5.0, including .5 KHz of PL tone. THen adjust the repeater receiver (repeat audio). Ideally there will be no gain or loss across the repeater.

Now to IRLP. Adjust the transmit audio out of the IRLP node using the 'audiotest' command. This sends a steady test tone followed by a short speech, and another test tone. The test tone should end up about 3.5 KHz on most repeaters in the U.S.

Once the transmit audio is set, use the echo reflector to set the node RX audio. Ideally there will be no gain or loss up and back to the echo reflector. Don't forget, IRLP never decodes touchtone "D" So the D can used to get generate a steady state tone to measure against, since the node never mutes a "D."

There is additional IRLP audio setup info at http://irlp.kc6hur.net/audiolevelsSM.php
