Re: [Elecraft] K4 - VHF/UHF
Will there ever be a VHF/UHF radio? I'm sure because of the cost factor there would a limitation. The interest would be the next question. Had to ask...

Too many surface mount devices. Not everyone has that skill for that kind of kit.

[Elecraft] Fw: Re: Expected voltage reading K3 Display ? at full RF output.
Hi Cliff, 1.0 V sounds about right. This all depends upon the length of wire and size. Assuming this is a regulated supply (switching or linear) and rated for your radio voltage and current wise and you don't remote sense, then the total length and size will determine the voltage drop. Good Luck 73, Brian K1DIH -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Clifford Hynds Sent: Friday, May 03, 2013 1:52 AM To: elecraft@mailman.qth.net Subject: [Elecraft] Expected voltage reading K3 Display ? at full RF output. Just a general question, thought my new power supply was dropping voltage on TX but no it is rock solid, I get about 1V drop at full power CW on the K3 Display. Is this normal, I have already replaced the troublesome PA pins is there something else that would cause this. Don't think the drop over the power lead would cause it Any ideas appreciated, Cliff VK2CCJ __ 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 __ 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 __ 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
[Elecraft] Fw: Re: FT8 - was "On Second Thought, I'll Take The Stairs"
Has anyone tried TeamViewer using the mode FT8? Was in QST a couple months ago. Just another facet of this great hobby. 73, Brian K1DIH That's one of the great things about Amateur Radio.

I hope that is not the next Goldilocks mode in the pipeline. I assume proponents of such a cobbled up "user interface" would feel perfectly justified in "sharing" even more CW frequency space?
