[Elecraft] KX3 SSB ALC Mic Gain - a new problem

2017-10-07 Thread Dr John H Farmer
Hi All, Apologies if this question posts twice - my attempt yesterday was unsuccessful, so here goes again. I've been running KX3 #2511 for several years on SSB with the MH3 mic and with settings: Mic gain 35 and compression 12. It's worked flawlessly and that combination of settings has

[Elecraft] [K3] MFJ-1786 Antenna

2014-09-06 Thread Dr John H Farmer
Hi Dave, I've used an MFJ 1786 for some years now and my experience has been positive. It's not a beam at 100ft, but over many hundreds of QSOs, the reports I've received and sent compare favorably with a wire doublet up at 40 feet. There's a learning curve associated with tuning it, but once

Hi Gary, I had thought about re-wiring the fans with 2 pin Molex connectors ( I have a packet of them here) but took Harry's lead and trimmed down the 3 pin instead. It was easy and the result very neat - the plastic is soft and easily cut with a hobby knife. I cable tied the excess lead

2014-08-23 Thread Dr John H Farmer
Thanks Don. I appreciate the tips. The power and ambient temp calibrations check out OK. I'll try changing the fan setting and see what that does. I work only CW and once the rig gets up to the temperature threshold, after an over or two, the fan stays pretty busy thereafter. Leaving the fan

Hello Group, I just want to share my experience in case it's of interest to others. I have excellent hearing and I have K3 #5102 and while it's a rig with outstanding capabilities, the fan noise has always bothered me. My K3 has the Utec fans and even on low speed, there's something about the

[Elecraft] Noctua fan for the KPA500

2014-08-19 Thread Dr John H Farmer
Good question! I had a look, but couldn't find a Noctua fan with the same specs as the stock Sunon which came with my KPA500. I did find that the fan noise on the KPA500 was reduced by mounting it on a silicone gasket and I'm happy with the improvement it made, so will leave it at that.

[Elecraft] K3 Data Modes using SignaLink USB

2012-10-12 Thread John H Farmer
I've been using my K3/100 with a Signalink USB for nearly 2 years and, once set correctly, the pair work flawlessly. The instructions for power setting in digital modes are repeated many times on this reflector and were hard to miss when I went looking for help. Once you accept that it's the

Hello Group, I'm pleased to announce that K1 #2822 is born - after a long gestation. I had couple of hitches along the way, which I thought might be interesting to report: I got as far as the end of RF board Part 1 in the build and came to page 36 of the manual where I power up for the first

Hello all, I'm progressing on my build of K1 #2822 and I've hit a conceptual block in my understanding of an aspect of the alignment process. I apologise if this has been discussed before on this list. I've read through the archives and can't find a very clear explanation. I'm hoping
