Wayne-- I certainly appreciate your annoyance but please don't pull a "Beezley" and blow off viable products and valuable customers as Brian, K6STI, did when he got upset with piracy. If every store
I have often been asked where to get a copy of Laport's Radio Antenna Engineering. A classic antenna book, published in 1952 by McGraw-Hill. Edmund Laport was chief engineer of RCA's international di
I enjoyed K0HB's story about QRQ and have my own little experience to share. I was always a sucker for techie gadgets and when the AEA CK1 keyer first came out I had to have one. This was the one th
Mike, K4GMH Mike-- The reason I ask is that I did the power testing for the original article and ALL six bands were subjected to 200 watts carrier for 30 minutes. (IC-781 driving an 87A at 200 Watts
Mario, With all due respect I think it had nothing to do with luck. Ed designed the filters specially using the referenced capacitors BECAUSE they would handle the power. Ed was VERY insistent that t
Ken-- But ON AVERAGE it is true -- it is a 4-year cycle! ;-) It's like the sunspot cycle, ON AVERAGE it is 11 years long! Thanks to Finland that long gap between Seattle and San Francisco was average
I agree with Ken, WM5R, but would like to extend the analogy a bit further. Certainly radio contesting is a sport, including both endurance and speed aspects. But it is also a game of strategy, and y
I am very glad to hear that Mike, KC7V, is doing much better after his medical emergency with pulmonary embolus, associated with his flight from Brazil. Obviously there is an important lesson here ab
This has been a problem for many decades. I built a Crud-O-Ject back in the 70s and still use it. Here is an old note from the Topband reflector that is a better summary than I can do from memory. --

I once tuned across a western Pacific DX-pedition just as he said -- now listening for QRP. QRP only! So I turned down the rig to 5 watts and gave him a call. He was very upset because I was obviousl
Dear Zoli-- I am sorry to disagree with you in the extreme. I did much of the original testing (along with K3LR) on the W3NQN filters as well as additional testing on ICE and Dunestar filters, and t
Mario -- This may be part of your misunderstanding about the Dunestar and W3NQN filters. The Dunestar filters are NOT 7-pole but rather 3-pole designs. This info is taken from the Dunestar website. h

Hi, Rex-- Yep, I have tried GOOGLE and I have this manual. It is for the rotator itself and includes some info on the selsyn-style (old-fashioned!) control head. I have a number of these old control
You can STOP LOOKING! All of you guys out there looking for a manual for the DRC-1 can stop looking now! I found one -- and many thanks to the guy who gave me the copy -- MANY YEARS AGO. Yep, I had a
