Incidentially and as you may wish, there is an old circuit that is simple
and effective to add CW break in for a tr3. Did it 3 times and worked very
well. I beleive it is an old article in CQ mag.

The comment about the sideband filter in the TR 3 is not to be passed over
lightly. If you have a problem there, you are in deep trouble. I carefully
took the surrounding shield off my problem filter and repaired it, then put
it together again. I was lucky I didn't break something.
All the other comments, concerning historic equipment, TR 3 as a poor CW
rig, etc, are spot on.
Buy it anyway! These things keep us from going brain dead using multi-band
CB equipment.

Hi,
The deal killer in the TR-3 is the SB filter. They often go
bad on
one sideband, still get some thru, but way low. Check output on 20m and
on 15m, they should be close, and above 125 watts out. Actual value
could be more (hopefully), but will depend upon alignment. Normally 15m
output will be a little less than on 20m, but not more than say 20 watts
less, if the final tubes are reasonably good. You should be able to
load up to about the same plate current on both bands.
Other than that possible problem, the TR-3 can be a good rig for
SSB
operation, usually at a good price, also. S-meter often seems stingy,
just turn up the AF gain if needed, signals are there. Definitely check
out the p.s. and replace the bias filter cap at least.

Hi Guys ; Considering a fully functional TR-3 from the owner of 15yrs.
I've been invited to try it on the air at his shack before I take it.
Being a relative newbie to Drake equipment, is there any particular
areas to consider with the TR3 other than the obvious and general
operating condition?
I don't recall anything negative in particular about this vintage
radio. I will upgrade the power supply and finals..Anything come to
mind?
Thanks 73 de n8aft.

For one, it's a terrible CW radio...if that matters to you.

Should you buy a TR3? I think the answer
