HT1000 UHF off freq tx and rx

Ive just got a used HT1000 with bad rx audio and tx audio.
the rx audio sounds like hf ssb - your listening to a transmission on lsb but it should be usb, to put it simple it sounds like aliens

the tx is the same, after searching ive found nothing that somes close to this problem and a fix any ideas?

ive tried an speaker mic, checked the codeplug data etc... alignment time maybe?

Yeah, alignment time.

Sounds like a defective reference oscillator....

It may still work, but it's no longer on frequency either, and this will throw off RX and TX channels.

I hope your radio will show you affection after the repair is completed also...would be nice.

To borrow a quote from a friend.......Just work once, that's all!

for anyone interested, the radio was fixed -

it had a transcrypt voice encryption module installed, removed it and re-programmed the radio to suit and bingo !

Funny how a reference oscillator can magically change into a voice encryption board huh?

Glad you found and eliminated the trouble!
