Good morning,
I first want to congratulate the "crew" with the birth of a new TRCV. I hope their effort will pay-off one way or another. For me personally as a serious VHF operator (don't worry, also HF) I did have two issues with the K2 from which I hope they have been addressed in the K3. 1) When active on MS (Meteor Scatter) or EME (Moonbounce) you are running high power amplifiers (I guess) and low-noise preamps. To take full advantage of the low-noise preamps, they have to be mounted close to the antenna together with the coaxial relay. To prevent blowing Gas-Fets you have to have a sequencer. So, switch over the relay, get the Amp in TX mode and only then after a short while start driving the Amp. As transmitting is initiated by the transceiver (PTT or Key) the transceiver will just start to delivering power. The best way to tackle this problem is to make a TX-Request available on one of the connectors. If the sequencer completed it's switch-over cycle, the Request has to be Aknowledged (TX-Ack) to the transceiver. If, like most of you, don't need this option, a connection between the REQ and AKN would just "short circuit" this feature. (This was a very practical solution used by Ten-Tec. I had a Paragon for the last 18 years). 2) As could be seen from the reflector, the Noise Blanker of the K2 is/was an issue. I lived in urban areas for several years, and my experience was that it didn't do what I expected. Now I live in the open field, but with electric fences. It still doesn't do the job. My Drake TR7 ( I don't know how they did it) just kills all unwanted signals except the "lids". I wonder if the NB in the K3 could come close to the TR7-NB. I really hope so! I really love my K2 with it's extreme good Price/Quality performance. I think even Elecraft itself won't be able to beat this P/Q factor. But at the end, we are all like little kids; we want more.. a K3. 73's, Evert PA2KW Happy owner of: Elecraft K2/100 (SN4836) Drake TR7/R7 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
