I'd say no, you really need a 7S...

I finally got my Elecraft K2 on the air. :) Long story short, I bought it pre-assembled / used back in March, but when I tried it out I only got static. The radio is in mint condition, so I’m not sure if the original builder/seller ever got it working.... For a while was stumped, and regretted purchasing it. So I concentrated on getting on the air and making QSOs with the QCX transceiver I assembled.

My Elmer, Ken, took the radio into his shop and correctly diagnosed and repaired all the problems. He used calibrated test equipment to get the radio correctly aligned. All I can say is WOW. It’s so quiet and can pull out the weakest signals from the background noise. Ken showed me the K2 alongside some of his high-end rigs, and the K2 was just as quiet and had just as clear of a signal. The K2s a pleasure to just leave on and listen to. Although I still really enjoy the QCX, going from the QCX to the K2 is a bit like going from a 2-stroke moped to a Rolls Royce, at least in terms of noise.

Here is the battery I picked up from getfpv.com.  I had to buy the buy the battery tester / voltage alarm off amazon.com.

Got any good ideas on how to hook this up to either a 320 or351?  Is 22.8 volts enough to power the radio?

Thanks as always in advance

Hello. I have been thinking about buying one... I heard there is a slight harmonics problem but aside from that they are great. I would use three 18650 cells, or four if it can take the extra voltage... If the QSX kit wasn't coming out, presumably soon, I might have bought one already.

In UK there are huge restrictions. I rent a flat(apartment) and have no access to the roof or land, only to small balcony... I have recently stumbled on a YouTube video(https://www.youtube.com/watch?v=UEwZ3MoKyUw) where author loads up a guard rail! Now the question is: can i load up steel framework of "my" balcony? The catch is that it welded together and to the re-bar of the building, witch is grounded....
Any experience to share?

Radio Reviews, Questions and Comments. / Ctx-10 vs. KX-2?
« Last post by Sig Man on May 30, 2019, 07:48:43 AM »
I`m looking at getting me a new portable radio, for both cw and ssb, and maybe digi.
The transceiver should be lightweight, internal atu, intrnal batteries and cover at least 20-80m bands.
I`ve got a kx3 and a kx1 (with atu and 30/80 module), the kx3 is to bulky and the kx1 is missing the ssb.. I really like the simplicity of the kx1, I like stuff that works without having to digg into a menu.

Kx2
+size and weight
+elecraft
+many users
-pain in the b... to recharge the batteries without ac-power

Ctx-10
+internal charger
+accepts 5-20 vdc
+looks more rugged
-few users
-a non ham companu
-size and weight
-fewer options in the menu

What is our thoughts of these to transceivers?

Antennas / Re: EFHW QRP radial?

Hello,

Radials are not necessary for half-wave end-fed antennas. You essentially will detune your antenna with radials. It's already a half wave, no need to add more wire. Some say that a short 0.05wl counterpoise helps, on 40m that's 3.3ft... I have never needed one. Radials are for quarter-wave verticals, not half-wave wires.

Bonjour. Difficile mais pas impossible. Je ferais sans aucun doute d'autres vidéos en Français sur le sujet..

73 à toi Gil,

Très bonne video mais j'ai pas tous compris  :(
Pourrais-tu gentillement faire la même dans la langue de Molière?

Merci beaucoup!
