Original Message Subject: Re: [Elecraft] K2 - How good on SSB? Date: Fri, 16 Mar 2007 12:05:31 -0500 From: RC kc5wa [EMAIL PROTECTED] To: Curt Milton [EMAIL PROTECTED] References: [EMAIL PROTECTED] Curt Using my K2 #4948 @ qrp ssb 9watts I worked 42 of 50 states on 80/75 meters. The microphone used was 600 ohm impedance RS Highball II. Antennas used an 5btv and dipole at 12' bent around an urban lot. Difficult but doable. YMMV RC kc5wa Curt Milton wrote: Very interesting question. When sunspots were good, i never hesitated even on 20m (unless there was a huge pile-up) to speak into the mic of my QRP K2. It rewarded me with lots of QSOs (using a vertical antenna). Recently I decided to check out its IF filtering across busy bands in the ARRL DX SSB contest. The narrower settings on the main board filter did do a good job of reducing QRM, as it improved with each toggle from 2 to 1.8 to 1.6 settings. Things I don't know are: (1) How well the K2 shape factors of the main board filter compare to typical 1.8 kHz accessory filters in higher end rigs. Note these typically have a wide ~ 2.4 kHz or wider stock filter and a single selectable narrow filter. (2) How well the K2 speech processor works in comparison to other rigs. I have no reason to discern any limitations for these - i just don't have any information other than casual use. At one time I thought that not having passband tuning (IF shift) was a 'big limitation.' But now I realize its only a big factor on SSB when your filters is wider than needed (as is on many lower end HF rigs). Some folk have set their SSB filter up to be a quasi-IF shift by having one oriented down and one oriented up on say a 1.8 kHz BW -- but I can't say this is the best use of the 4 available settings. (Gee - I know the enterprise would appreciate you buying a second K2, but you can only do one mode at once. No reason why your existing K2 can't be a CW QRP machine, a SSB machine, and by flipping the lid also a 100w multimode rig. ) 73, curt - Original Message From: Fred (FL) [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Friday, March 16, 2007 11:35:05 AM Subject: [Elecraft] K2 - How good on SSB? Thinking about building my 2nd K2. First # 54xx, was a very sucessful build. Does anyone have thoughts on how well the K2, operates, by itself, as a SSB HF rig? It would seem 15W is kind of pushing it for a suitable signal - but just wondered if any successful K2 SSB ops are around.

[Elecraft] Historical pictures
Thanks Ron for the memories from the past. As an (over-nite)EX-DJ I used a head set that was plugged in to a FM Receiver instead of the control board. It allowed me to hear my actual on-the-air signals as opposed to the control board input to the transmitter. It just made more sense and easier to quickly spot transmitter problems. It also meant I was not tied to the control board. RC kc5wa http://www.kc5wa.us ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KX-1 Q1 Bad - Now no received signal / RF Gain
I believe that the J309 is pretty much interchangeable with a J310 or MRF102. At least I've done this with no change in other circuits and operation did not seem to suffer rc kc5wa Rich Holoch wrote: I had my KX-1 receiver working beautifully through the first 2 stages (up through getting the receiver to work), then I added the last components - for the transmitter. I turned it on to complete Test III, and there was no received signal. Everything but the RF Gain control works. The audio gain and and filter control respond just like before, keyer works, strong sidetone and audio, frequency encoder works, bands switch just fine, etc. I checked all components and sure enough - Q1 was in backwards. I tried to unsolder and put it back in, but I am sure it was fried. After putting it in correctly, voltage was OK on 2 or the 3 connections - the third was zero volts. So the JFET must have opened. I'm hoping that just by replacing JFET Q1, the receiver will work again. Is it possible that by having a bad Q1 that that could cause no signal to be detected in the receiver? When I look at the schematic, I almost think that the receiver should still work even with Q1 out of the circuit - is this a correct or wrong assumption? If it still should work, then there might be more wrong than just Q1.
