Good Morning All, If you take a moment to click onto this site http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=220185518740&ssPageName=STRK:MEWA:IT&ih=012 it will become readily apparent why I'm experimenting here with the notion of using a dedicated RF signal generator as a replacement for any HC-6/U band crystals at the back of my "new" R-4 receiver!
With days still to go on this auction, it's already approaching the price of the entire Drake Twins station that I purchased here the other day... BTW, the notion of a signal-generator-cum-crystal-substitute is a viable one: I played about with mine yesterday, and managed to copy all manner of shortwave & medium wave stuff on the rig, "...for free". The injection level of RF voltage into the crystal socket is important, though: I obviously never had enough "soup" from my WW2-vintage generator, because S-meter side-by-side comparisons --- i.e. the signal strength of a BC station, crystal vs. generator --- showed that I needed a lot more "horsepower" out of the generator than it was capable of delivering... A solidstate, compact generator --- with a built-in crystal calibrator --- is in order here for casual SWL'ing. For the Ham bands, though, I still prefer the "rockbound" route... ~73~ Eddy VE3CUI - VE3XZ
