[Hammarlund] Preselector suggestion?

[Glen Zook]

Not only do they QSL, but many send a QSL just as soon as you finish the contact.  Then, about 2-weeks later they send another "just in case" the first one doesn't make it.  Finally, after you send a QSL they send another thanking you for your QSL!

I like to run JA's on 40CW during evening grayline longpath, the din is 
amazing.
I'll call one CQ and just run them until they are well into daylight and 
fade out.

Of course everyone QSL's!

Just about all prewar radios need some preselector help at 12-14MHz and up 
and a lot of the 1945 to roughly 1954 ones. Once the 6DC6 and 6BZ6 were used 
in front ends it was only necessary from about 20MHz and up.

Even the R-390A is a bit noisy on 10M.
