Eric, Hallelujah! First acknowledgment of such a possibility! I vote to put a second amp module in the RF Deck (i.e., an RF deck that is the same as the total size of the KPA500) and have a separate switching supply in another box. 1200-1300 watts would be a sweet spot if 1.5K is a problem.

This debate seems to get resurrected a lot. I think the reason for that is more philosophical than technical. Clearly 1 KW is better than 500 watts, at least in many cases. The question really is, do you actually need it, and can you make that leap practically. Answers to those questions

Interesting discussion. Folks, if we did introduce a 1500 W solid state amp similar to our KPA500 in operation, what features etc would be important? 73, Eric /elecraft.com/ __ Elecraft mailing list Home:

Dwight, I suggest using serial port servers for the SPE, rotors and any other serial port devices. If you use these along with the RemoteRig boxes, then you will no longer need to have a PC running on the radio side. The RemoteRig boxes have two serial port servers built-in, but are both

Not sure about the Palstar but the SPE should be fairly easily controlled via its USB interface, So I would suggest a small and inexpensive PC like an intel NUC at the remote site that will open up a number of advanced features that will be difficult to tether over an Internet connection. Ill

The expert amps work great with the K-line. I use a 2kfa for contesting from K6LRG and the only equivalent amp I would put it up against is an ACOM 2000. It is essentially the Solid state equal of the ACOM but has more capabilities. The interface is excellent. Amongst my colleagues there

I have noticed recently a change in the audio in my KX3 and I have not knowingly changed any settings. The audio is very low, especially in CW, even with AF up to 60. I do have the RF gain to the maximum level with AGC-Fast and preamp on. SSB is a bit lower as well, but not nearly as bad. I do

I have a 1500 watt alpha sitting in the corner. It is a great amp, although, I don't like the clunky relays and the fan noise to cool the tubes. Once in a while I like to not have to use cans to operate, but for the most part I do use the headphones. After having the Alpha and SB 220, and TenTec

Re: [Elecraft] K3S front panel remove/replace tips?

2017-03-17 Thread Ian White
When separating the front panel assembly, place the K3(S) upside-down on a smooth anti-static mat [1]. This ensures that the front panel cannot drop away when the two units come apart, and avoids bending any connector pins. Likewise when reassembling: place the two units upside-down on the mat,
