Hi Evan and everybody on the list,
My wife and I will be coming over to this year's Dayton Hamvention. The
planetickets were booked today. We are looking forward to meet many of you at
The Drake Forum!
We will be arriving to Atlanta, GA, on Wedneday May 13, and our departure will
be on Sunday M
Hello,
Did anyone read the article on modernizing a TR-7 by DK4DDS. It has
information on adding a ton of features, such as DSP Noise reduction, curing
the PTO Drift, Notch Filter, Improving the sensevity on the higher bands,
Speech Processor and a bunch of others. It is some great food for th

In a word, YUK!
It's like jacking up a Jeep and putting a Corvette engine, transmission
and wheels under it. What you end up with is neither a Jeep nor a
Corvette, but a collection of parts.
Much better to sell the TR-7, take the money you'd spend on the

Agreed Garey! I have a better suggestion though: keep the TR7 and if it is
so needed, buy that ugly ricebox in addition. Soon finding out that it is
nice to go back to the TR7 from time to time :)

You said it, Garey. What a terrible idea. It's a waste of a radio, time,
manpower, and money.

I think you need an additional opinion on this! First, the QST article is a
very poor condensed version of the DK4DDS (PA1HFO) mods that have been
floating around for a few years now. For some inexplicable reason, many of
his solutions were left completely out of the article (e.g. solution fo

I may remember someone in Europe using them in Drakes. It would either take a

combination (not that hard either). Some day we may be grateful to get

The meters in my TR-3 are very bouncy. They are also magnetically coupled
together, so one will drag the other a bit and cause more bouncing. I was told
the early meters did this. This may be different than your problem.

Well, it's obvious that the "original configuration" is obsolete and
needs to be replaced by a piece of silicon!! :-)
Actually the flashing in VR tubes is often seen with leakage of air past
the pin seals. I have had several NOS tubes that have exhibited this
behavior. You may need to try

The rest of the mods are shown in the "Extended" version of the article
on the ARRL Binary site.
Certainly there are mods that can improve the TR-7 over what was
"do-able" almost 35 years ago. I just _personally_ prefer to use
these and other "period" rigs as designed. Things lik

I had the same behavior in my early serial R4-B. It's quite a light show in
a darkened room. The cause is definitely a bad VR tube in which there has
been air ingress. Just stick another tube in there.

I will admit the DDS VFO idea looks interesting, and I understand they
