K7GT obviously has the same concerns. Over the past decade I've used a slew of Ten-Tec and Yaesu xcvrs interfaced to Ten-Tec, Alpha, and Acom amplifiers via plug 'n play keying loops with uniformly excellent performance.
The lack of QRO QSK with the K3 may be a big issue with some prospective K3 contesters. 73, Barry N1EU >Don, in the email below, says that the time delay in the K3 will accommodate a QSK amp. That is only partially true. The problem is in setting it up. I could, of course, put in a LONG delay but then QSK is gone. If I crank the delay down, at some point I am relying on the RF sensing circuitry in my QSK amps to hold the relays closed until RF is really gone from the input. That may work but I would really prefer the sure-fire solution of a keying loop. This allows a QSK amp to be set up optimally by just plugging in and does not require a scope and a bunch of fuss. The QSK of my Tentec transceivers coupled with either the Titan or Hercules II QSK amps is plenty fast for me as I never go above 50 wpm anyway. >For what it is worth, the Yaesu transceivers and their Quadra QSK amp use a keying loop. It works great also. We used it in SS this year and had a ball. I> am sure that the K3 will key perfectly with the yet-to-be-available Elecraft amps, but it would be nice if interfacing with existing QSK amps could be done in the obvious way. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
