Alinco DR-135 TX AUDIO alert
- We have four Alinco DR-135's here,
three have failed the TX audio, one was sent
back to Alinco and it came back repaired.
Of the three failed ones, one was used with the DB-9
port in back for audio (a crossband repeater setup).
The other two were regular radios using the mike. But
when the mike audio failed, it also would not work with
audio into the DB-9. Those two units are also at
Alinco repair depot as we speak.
Another thing that happened to us is the screwdriver
used to adjust the audio gain. Turned out it goes into
the pot just fine, turns the pot just fine, but when it
is removed it takes the adjustment knob/rheostat wiper
out with it, ruining the pot. That is not Alinco's fault,
but is something to watch out for. That was another
$70 here, $70 there, pretty soon you are talking big money.
If your radio seems not to transmit, you may want to check
your tx audio and make sure it is not the radio giving the
problem instead of the TNC.
We think that the Alinco DR-135 is a great radio, but this is
one of its quibbles.
