son and I did together. Who says hams don’t have other connected interests?! Life is full of adventures, what are some of your ham inspired activities?? And after almost 54 years of hamming, finally made it to Dayton the last two years! 73, Roger VA1RST, K7SJ, WA7BOC K2 755, K3 75 Sent

Thanks Don, I’m on a Pro Audio Engineering supply output is 13.5 key down at full output. Although not a be all tell all, I was monitoring RBN at the time to see where I was being heard and it was reporting my frequency correctly. THanks! Roger > On May 8, 2018, at 6:21 PM, Don Wilhelm &l

[Elecraft] Strange PX3 issue

[Elecraft] KX3 SWR Meter vs MFJ

I decided to do a spot check on SWR readings on my antenna with my KX3 after I tuned it with a MFJ 259C. The results were different between the two devices.  The MFJ on the lower bands read a significantly higher SWR than the KX3.   I guess my question is which would you trust, the MFJ or the

Re: [Elecraft] OK, odd question

IIRC there was no "standard". It was an arbitrary choice by the manufacturer which side of the filter they put the BFO crystal frequency. Nice to have a choice with the K3! 73, Roger On 2/14/2018 11:15 AM, Chuck Chandler wrote: Something that bugs me just a tiny wee bit. So, f

[Elecraft] Selectivity

I noticed that during the contest, that if I selected 50 or 100 Hz selectivity, the audio would drop way down. It didn't used to be this way. I tried reloading an earlier version of the software but couldn't figure out how to do it. Hope this comes through, finally! 73, Roger
