Rci 2950 no audio period rx or tx

I think you will find the problem is in one of the microphone wires. The switch for TX/RX is in the mic, and if the RX wire opens up, you will not get any receive audio.

1. Ground Shield
2. Audio Yellow
3. Transmit Red
4. Receive Black
5. CH. Up White
6. CH. Down Blue

have you tried it on all bands? still won't transmit?take it to a tech so they can fix it properly.

check your mic cord to see if you have a broken wire on the inside.You might want to get another mike for a spare but it could also be an audio transister.

i have the same radio rci 2950. Ive had the same problem with mine,turns out with mine the processor would lock up,turning the radio off & on repeadly would clear the problem and the radio would work fine x-mit & recieve. the solution to fixing the problem is to replace the memory backup battery this battery works similar to a computer motherboard cmos battery when this battery goes dead all sorts of strange things happen to the radio wont transmit wont recieve or like your problem transmits continiously. the problem with replacing this battery is finding out what year & model your ranger 2950 is. the internet says only first generation ranger 2950s use the battery second genration & third generation do not use the battery. but the internet could be wrong. so i suggest getting a hold of (usa ranger.com) & give them a phone call or email and ask them about the year your radio was made. they may even service it for you or if you are electronic savvy you can do it yourself. the battery is located close to the main cpu on the front panel if yours uses a battery.

Do you have receive? If so you might have blew the voice chip. If you don't have receive or transmit you most likely blew those final transistors.

could be a number of different problems causing this. I would start with your microphone make sure it is working. it is responsible for transmit & recieve. next check to see if the memory battery is dead this will also cause this problem. next check the regulators in the radio to see if they are supplying voltage.next check voltages in different parts of radio to see if all stages are recieving power follow these steps and something will show up also check your switching diodes to see if they are bad the diodes responsible for x-mit & r-mit of transceiver.

If the radio is not going into TX, then you have not connected the TX line back up,

If there is no audio when you TX you have left the audio wire off.

The radio usually needs 4 wires.
TX (Puts radio into TX)
Audio (this carries the audio from the mic into the modulator)
Screen (ground cable (earth))
RX (not as common these days)

No. Tx/Rx Description
##0100 [Tx] at time of transmission, the procedural signal has been transmitted more than
specified.
##0101 [Tx/Rx] the modem speed does not match that of the other party.
##0102 [Tx] at time of transmission, fall-back cannot be used.
##0103 [Rx] at time of reception, EOL cannot be detected for 5 sec (15 sec if CBT).
##0104 [Tx] at time of transmission, RTN or PIN is received.
##0106 [Rx] at time of reception, the procedural signal is received for 6 sec while in wait for the
signal.
##0107 [Rx] at time of reception, the transmitting party cannot use fall-back.
##0109 [Tx] at time of transmission, a signal other than DIS, DTC, FTT, CFR, or CRP is
received, and the procedural signal has been sent more than specified.
##0111 [Tx/Rx] memory error has occurred.
##0114 [Rx] at time of reception, RTN is transmitted.
##0200 [Rx] at time of reception, no image carrier is detected for 5 sec.
##0201 [Tx/Rx] DCN is received outside the normal parity procedure.
##0220 [Tx/Rx] system error (main program out of control) has occurred.
##0232 [Tx] encoding error has occurred.
##0237 [Rx] decoding error has occurred.
##0261 [Tx/Rx] system error has occurred.
##0280 [Tx] at time of transmission, the procedural signal has been transmitted more than
specified.
##0281 [Tx] at time of transmission, the procedural signal has been transmitted more than
specified.
##0282 [Tx] at time of transmission, the procedural signal has been transmitted more than
specified.
##0283 [Tx] at time of transmission, the procedural signal has been transmitted more than
specified.
##0284 [Tx] at time of transmission, DCN is received after transmission of TCF.
##0285 [Tx] at time of transmission, DCN is received after transmission of EOP.
##0286 [Tx] at time of transmission, DCN is received after transmission of EOM.
##0287 [Tx] at time of transmission DCN is received after transmission of MPS.
##0288 [Tx] after transmission of EOP, a signal other than PIN, PIP, MCF, RTP, or RTN has
been received.
##0289 [Tx] after transmission of EOM, a signal other than PIN, PIP, MCF, RTP, or RTN has
been received.
##0290 [Tx] after transmission of MPS, a signal other than PIN, PIP, MCF, RTP, or RTN has
been received.
##0670 [Tx] at time of V.8 late start, the V.8 ability of DIS front the receiving party is expected
to be detected, and the CI signal is expected to be transmitted in response; however,
the procedure fails to advance, and the line is released because of T1 time-out.
##0671 [Rx] at time of V.8 arrival, procedure fails to move to phase 2 after detection of CM
signal from caller, causing T1 time-out and releasing line
##0672 [Tx] at time of V.34 transmission, a shift in procedure from phase 2 to phase 3 and
thereafter stops, causing the machine to release the line and suffer T1 timeout.
