I have a fairly new 6600M and once had the PowerGenius on order, but cancelled after it was delayed and my transceiver was ready. I'm thinking that the Elecraft KPA1500 is the only full power solid s

Jim, I did locate the Finder datasheet on the Newark/Farnell website. Watch for text wrap: http://www.farnell.com/datasheets/2611932.pdf?_ga=2.102231233.1928605109.1538931238-590108331.1506213021 Not
Tnx for the info, Paul. Yes, in principle 7mS is fast enough, but the data sheet doesn't specify contact bounce which, for this type of relay typically adds another 4-7mS. Even vacuum relays (excepti
Considering how much care went into the design of the Flex amplifier, which in many ways is quite remarkable, it?s surprising how basic CW operation seems to have been shortchanged. Could it be that
Ditto what Jim said about the B26 2K+. I'll add that the heat sink has serrated fins to maximize contact area with moving air. The never exceed temp, the temp at which the amp shuts off, is 72C. NG7M
Although 12V vacuum relays are available, W8ZR came up with an elegant solution that I hijacked for use in my S-QSK controller. A 12V muRata DC-DC converter is bootstrapped to the 12V power supply t
Just because you don't operate CW doesn't mean there isn't a market out there for a CW amplifier. "More than 10,000 logs have been submitted for the CQ World Wide DX Contest, according to Contest Dir
Tom, Just because you don't operate CW doesn't mean there isn't a market out there for a CW amplifier. I fully agree on that. The question is just how large that market is, compared to the market for
How much can adding QSK to a Mega-Bucks Amp cost ?? A rather small percentage of the purchase pride I expect. Sounds more to me like the bean-counters are ruling the roost. 73, Dick, W1KSZ __________
Most CW ops that do not use full QSK do operate semi-QSK. And in that case the delay between the amp key signal being asserted and the t/r relays closing and settling reliably is just as critical as
<<I fully agree on that. The question is just how large that market is, compared to the market for an amplifier without QSK capability but slightly less expensive. <<That shows how very few hams enga

I realize I'm just one example. I used to operate almost exclusively CW and my speed topped out at a bit over 40 WPM, but typically I'd run a bit under 30. Copy by ear and used an electronic keyer.
Roger is correct. Fast (semi break-in) works very well and is better and safer for equipment than QSK. Additionally, I have seen the same issues with speeds above 35WPM in some cases. On 10/16/2018 1
It would be interesting to d a study and see just how many CW op's actually work QSK. I've been on CW since '54 and have never used it (except back in my CW traffic days with a separate antenna on th

I don't use full QSK for ragchewing or running stations, in which case I use semi-QSK with a short delay adjusted to allow the relays to open between words. I do use it when I am trying to work a DX
