[Elecraft] 9M6XRO with my K2/10
Today, there was a pileup on 9M6XRO (East Malaysia) on 10 meters. Using my K2 at 5 watts (my antenna was a Cushcraft A3S at about 24 ft in elevation) I got through the pileup on about my third call. What a surprise! It's the first time I've broken through a pileup on QRP. What fun!!

Re: [Elecraft] [K3] Detuning Antenna Per Band and QSK
Earlier I suggested PIN diodes for this purpose. Upon reflection (no pun intended) I realize the one would be hard put to find PINs that have the carrier lifetime to function at 1.8 MHz. I think that a vacuum relay might do it, but think that sequencing everything wouldn't be trivial. All of that said, another possibility would simply be a series diode switch with enough forward current to keep it on over the r-f cycle. During receive it might not even need reverse bias. (There's no transmitter power to deal with) You don't necessarily need high isolation, just enough loss to attenuate to lower the efficiency of the inverted L during reception on the beverage(s). Of course, it may be that none of this is necessary. The inverted L on receive is terminated by the 7/8" Heliax transmission line back to the KAT500 (I happen to know this is what is in use) and whatever load it sees on its input. This could be anything.

Re: [Elecraft] Heil HC-7 Dynamic Element with K3/0 Setup
The Heil page suggests LOW not HIGH. I have, and sometimes use, a PR781, which is one they mention along with the HC6, and I use LOW. My settings for the PR781 are intended to make it more like an HC4, which is what I use for DXing. I cut the lows more and emphasized the highs more than Heil's settings. Being a retired accountant, I keep Excel files of the mic settings (and menu/config settings, which are in the Elecraft_K3 yahoo Group files area).

Thanks. I already tried that and the DVR recordings sound absolutely fine.

The reports on my audio are terrible, so I must have something setup wrong. The audio is very low, and appears to have some background noise. My Heil headset with an HC4/HC5 mike element is a little better, but still low, on both elements. In contrast, my Elecraft MH-2 mike sounds great and gets great reports. It has much more audio output. I am operating remote from Key West using a K3/0 mini and RemoteRig to a K3 located in Maryland. I have mike bias on, but on or off makes no difference. Thanks for any suggestions. 73 and Happy Holidays, Brian W3BW *Brian F.

Re: [Elecraft] New K3 beta firmware release, rev. 5.01: Much-improved audio during CW keying
Hi Gary I hear it as you do. The amplitude of the transient depends on the received noise level. This can be demonstrated with the rf gain control, but setting the gain control low and then increasing the received noise level with eg a preamp brings the transient back, so it's the actual noise level, not the rf gain setting. The transient we're hearing is also there on semi break in, it's not restricted to qsk. But it is a huge improvement. Graham On 19:59, Gary Smith wrote: Graham, I agree. And I also hear a "transient click" albeit it far better than before. Since you hear it as well, I have to ask you if you hear it on the right side, not the left, yes If you play a character slowly, do you hear it at the end of the character yes and if it goes away completely if you engage the sub Rx? yes This is what I have found with my K3. 73, Gary KA1J __ 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
