"Al Parker" <[EMAIL PROTECTED]> made an utterance to the drakelist gang
----------------------------------------------------------------------
Hi Jason,
There are instructions on "setting the tweet" in the receiver manuals.
IIRC there's more than one method given, I think the following has given
me the better results:
==============
Setting the tweet:
-----------
control or switch posn R-4 (A or B) T-4X (or B)
=============== ========= ========
band 3.5 3.5
function slow AVC SSB
passband 4.8, w/knob at ----
12 o'clock
audio 1 o'clock ----
transceive ---- Spot
sideband ---- set to SB
that gives
the
loudest "canary" sound
preselector Both xmtr & rcvr on abt 6.5, but adjusted for the loudest
"canary tweet" from the spkr.
adjust C-61 to make the note come to zero, the tweet slows way down, you
want to get it to a few chirps/second or less.
if it's way off, you may need to move C-61 quite a bit, listen for the
beatnote to approach zero, that's the tweet, once you've heard it you'll
understand, but it's a bit hard to recognize at first.
