Good Evening, Conditions were better than they have been in some time. Quiet on twenty with a few storms active on forty. QSB was low to moderate. I did not hear any digital activity. The sun is slowly waking up.

[Elecraft] Loop antenna replie
I would like to thank all who applied to my loop antenna and attic antenna questions; you have given me a lot of good ideas and things to consider and I appreciate it very much!

[Elecraft] 80M SSB Net for October 24th (25th UTC) 2021
I unofficially ran the 80M SSB Net this evening starting at 0102 UTC and noted the following check-ins: Call Name StateRadio N8SBE Dave MI K3S Net Control AE6JV Bill NHRelay Station WB8HROTimMI FT450D NC0JW JimCO WB3LGCSteve DE K4D Sorry, I didn't note everyone's radio. If you have additions/corrections, please let me know. Propagation was not especially good this evening, and there was a great deal of lightning QRN from a line of storms over Illinois extending south of St. Louis. I appreciate everyone's patience as I dealt with all the static on my end. The net concluded at 0124 UTC Dave N8SBE __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K2 K2 QSK?
Jerry, There has been a LOT of discussion on the K4 groups.io forum about the QSK performance of the K4. If not subscribed to that forum, it's worth doing so if only to follow the chatter about the K4's features and reported bugs. Follow Don's advice, especially on any matter involving the K2! 73, Mike, K8CN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K2 K2 QSK?
Jerry, Your K2 #1 DOES have AGC - it is built into ALL K2s. There are 2 possibilities - 1) the AGC has been turned off - that is a 2 button function of PRE/ATT button and the AGC button pressed at the same time. Normally just using the AGC button changes between FAST and SLOW. 2) The AGC threshold is not correct. If the serial number is 3000 or above, there is a pot (R1 on the Control Board) to adjust the threshold - see the K2 manual for where to measure while setting it. There are 2 VFOs in the K2 although only one is displayed at a time. A simple tap of the A=B button will sync the 2 VFOs It sounds like you might benefit from downloading the K2 Quick Reference from my webpage www.w3fpr.com. Look near the bottom of the homepage. There is a lot more function to the K2 than meets the eye. You will have to get the answer to your QSK on the K4 from someone else, but I expect it to be superb - I know both the K2 with the K2 Keying Waveshape Mod (SN 4660 and above) and the K3/K3S have excellent QSK keying, and I expect the same with the K4. Unfortunately, the K2 Keying Waveshape Mod is not available from Elecraft, but Dave Van Wallaghen W8FGU was talking about providing a kit for it. If your K2 does not have it, I would recommend contacting Dave. To check your K2 for the presence of that mod, remove the bottom panel and look at D36 - if it is a clear PIN diode or a PIN diode mounted on and SMD carrier board, the mod is installed. That mod is important for preventing keyclicks which are not noticeable for the QRP K2, but become obvious with the KPA100 (or other amplifier). 73, Don W3FPR On 10/24/2021 3:52 PM, jerry wrote: So: Somehow I wound up with two K2s. I bought the first one because it was small - multiband - and QSK. I have become enamored of transparent, conversational QSK - the kind where your transmitted signal just sounds like all the other signals. The K2 alas is not that, although it is PIN diode switched. I don't think any commercial transceiver is. Got K2 #2 to get the KPA100. Moved the KPA100 to #1, because #1 has all the good mods - the PLL mod, the volume control mod, the upgraded crystals, etc. The closest I have been to really good QSK is a QRP-labs QCX+ kit. But it's only one band, and the receiver is probably not as good as a K2 with a crystal filter - and K2 #1 even has the DSP audio filter. AND it lacks AGC. I was operating field day, a local came on and nearly blew me out of my chair :). So here's my idea for perfect QSK: I use the two K2's as a transmitter receiver pair. One on transmit, the other on receive. Connect them to the antenna with a custom PIN diode switch. W6JL has a lot of info on that in his QRZ page. Arrange something like 130dB attenuation or whatever 100W ( or 500w if I use a linear ) down to a microvolt or two. HOWEVER... I really don't want to be synchronizing VFOs all the time. So I find some sort of open source transceiver control program. And modify it so it tunes TWO radios at the same time. How good is QSK on the K4? Smooth/transparent? Or clicky-choppy-AGC-pumpy? __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

[Elecraft] Can we get back to Elecraft topics?
While I've found the RFI discussions very interesting it is adding a bunch of 'noise' to the mailing list, can we circle back to Elecraft focused topics?
