I don't knock any team I am on. I presume the team at TenTec is doing its best to survive in a difficult economy. I further suspect it has cut costs to the bone and more than one employee now wears m
Good Evening, Jack -- Thank you for the extremely thoughtful and detailed reply. I now fully understand your position. Happy trails. -- K8JHR -- _______________________________________________ TenTec
YES YES YES THAT IS EXACTLY THE PROCEDURE I WAS REFERRING TO! WELL SAID, GH. While many hams use a desk mounted mic, I am a headset junkie... and use various headsets with either open or closed earph
with a well-regulated supply volt has of 14.9 V. I found that at 13.8 V, output on 10, 12 and 15 m was lower and more variable. it drew a bit more current on the 10 and 12 m bands, so make sure the
First thing I would do is check the voltage sag, and I would worry if you observe ANY substantial voltage sag. I heartily second Bob's (K4TAX) comments. Here is MY checklist developed after having a
This is an additional gloss on my previous post to be more fair to those with issues. To be fair, there IS a difference between providing new or upgraded features, and fixing problems with original f
I agree the problem may be inside the rig, even though a "symptom" is voltage sag at the power supply. But I disagree the problem is not a voltage swing, and disagree it would affect all bands equall
What is nearby that could be affecting the antenna? My aluminum dipoles often exhibit strange, wild swings with a change in position in the yard. Something nearby may be coupling and affecting it. An
For the 565, I had help from an anonymous ham _____________________________________________ Er... say, JH... If that anonymous helper was a volunteer, could I get you to forward to him a bottle of su
Kenwood has gone over to 4 pin power connectors on most recent models. I guess there is nothing sacred. -- K8JHR -- Kenwood radios have been using a 6 pin power connector for decades. _______________
OK... Roger. Funny I offered a bottle up to the first gathering of Arduino QRP-ers at the TT Hamfest, but no one took me up on it. Too bad for them as I was dead serious about it. Maybe JH and PC at
Hmmm... Maybe Mike ALSO has a friend with a different analyzer who can test it, also. More likely the difference in analyzer than a difference in yard stick ? -- K8JHR -- My suggestion is to have a s
For all the high technology that goes into these radios, it seems, to me at least, they have done precious little development on the power supply side. Not that you can improve on two wires, red and
You could make a simpler version of my SO2R switch... my device switches the key, mic, speaker, headphones, amp lines, and more, but you could simplify it to suit your needs. It would use a smaller b
Hmmm... It started in the 60s with UNIVAC... ... then came the KILOVAC ... .. and then came GIGAVAC... ... and now the Roomba-vac ;-) No telling where will it end? ;-) __________________ Anonymous __
You are testing with CW right? Testing with only the SSB carrier sometimes shows nothing. If testing with SSB, then talk or sing or whistle while you work... -- JHR -- Mike -- There is zero additiona
Mike told us what he has. The ARRL Antenna Book defines "doublet" as synonymous with "dipole," but I understand many hams intend the locution "doublet" to refer to a type of dipole fed with open line
I will forward this to a friend with a contest station... we already have a German guy on the team... and I think they usually work that contest, so maybe he could work it there, and it might be like
You old hands with more experience may know all this, but these detailed How To notes are invaluable for those of us who had other careers and who are relatively new at fixing radios. Thanks. -- K8JH
