"Tune for lowest!" BZZZZZZZZ!

Post by 9YCH-FM »

I have an older 5W stereo TX. I press the test button and the unit cycles
through 3 tests: all OK. Press again and the display reads "Tune Up".
Nothing seems to happen. Pressing a channel up or down button
causes that angry error message... even with a 50 ohm dummy load!
Any ideas?

Also, where to get a low-power VHF SWR meter?

I saw in an old post that "tune for lowest" means that I should adjust the audio pitch.

???

The audio from the radio reciever is *great*:)
Will I damage the TX if I ignore this error message?

Ah, yes, well- the papers were misplaced some years ago:(

At that time there was a group interested in forming a comunity station.
For various reasons, the group disolved and the TX was never used.
Now a new group has formed and, finally, things are getting started.

Perhaps I should take another look around the site- perhaps some
docs are online.

I assume you can transpose the output of the tuning test tone to some form of digital power output scale, for example a multimeter? for a more precise reading.

This method is very precise, an ear is a very sensitive instrument
when it comes to comparing two sounds in frequency.
