Hello Demis,
you may want to try reseating the DR7 first. I would say that EXACTLY 2
MHz offset indicate a digital problem. The relevant circuitry sits on
the DR7. The connector is on the upper left when the front looks to you,
9 Pins. If you have an intermittent there, it could cause the
Hello Gary,
I am not particularly familiar with the Signalink but it seems to have
the usual connections like AF-out, AF-in and PTT.
The TR7 is not at all uncommon in this respect. Keying is low-voltage
positive and the audio connections are not different from other
transceivers.
I used mine
Thanks Paul for sharing this!
I found the fast AGC on the R7 useless, too. I will try the proposed mod
on my R7.
@Jim, would you say that the service manual describes the right methode
for aligning the AGC?
I have had my doubts about it in the past, mostly because 'fast' would
always create
Hello Roger and group,
I had the same problem with an L-7 I bought some time ago. It came
without P/S, was cheap and had 3-500ZG with graphite anodes from RF
Parts. But I was aware of a short in the load cap because you could hear
it when turning even without RF applied. I bought the whole
Gentlemen,
I am currently after an L7 missing the power supply. It will not be a
big problem to build a decent p/s but will I be able to get that 8-pole
connector? Especially here in Germany it is probably hard to get. Can
you give me some sourcing hint?
Thanks and 73

Hello Drake community,
my R-7 is always jealous because the TR-7 sitting next to it has an MS-7 while
the R-7 only has the internal speaker.
So I am after another MS-7 to restore full fairness on the table again.
Should anyone of you have one for sale, please let me know.
Thanks
Dieter
Another 2 cents from across the atlantic. I have been on this list for

being present in the community here.

I agree with the ferrite idea. Whenever I go to the club station DL0AO for a
major
contest, I have a few ferrites with me. And they did help a lot

Steve,
my TV-3300 works just fine and I wonder why yours has the cut-off frequency
already on 10 meters.
If you know someone who has good measurement

Hello Ken,
I am afraid, it is normal. Reason is that when audio is completely muted, the
radio is off because the on/off switch is activated

Dick,
look at the VHF suppressor directly at the anode. It is usually made of
carbon resistors with a coil wound around.

Hi Vic and group,
some years ago I replaced a 'semi-faulty' transistor in the audio chain which
caused some
kind of noise or rumble.
Unfortunately, I
Hello Craig and group,
I had problems with oscillation on my TR7. Setting the predriver to minimum gain
did not help so I removed R2209 which is in parallel with the gain pot of the
predriver.
(I have board #2 with one MRF476). This further reduced gain and my problem was solved.
I am still
