Make sure you do not take any cell below 3V.

I used to use RG-174, but now I prefer RG-316, even though it is less flexible.

So how low does the 320 go?

I think that will be true at the beginning, when everyone still has charged batteries... After a couple weeks I think mostly QRP radios will remain on the air, which means more CW rigs.

I don't think the 817 needs defending. It is no doubt a great radio.

The Elecraft K2 only comes as a kit. You can find used ones. It is an 80-10m CW transceiver, which can be extended to 160m and SSB. There is even a 100W option. Power is 14W. I built one a few years ago and it is an excellent radio for CW. The receiver is very sensitive and had good filtering. It is not a particularly difficult kit but takes a long time to build because of the number of components. Elecraft still sells it but my guess is that 2018 might be its last year... Let's hope not... It does cost a lot new but is worth every penny.

Why do you consider it not a good platform for Morse code (CW)?
Probably because you need to buy an extra filter for CW, and the receiver isn't as sensitive. I never used one but I suspect it does work fine, just not as well as an Elecraft. No other radio offers as much in such a small package though.

I think around 400Hz works great.

Has to be a time issue. WSPR requires to-the-second precision...

Very good post Wally, thank you.

This is exactly what I am getting at... My recent experiments with 80m have been very successful. I was stupid not to have tried that band sooner because of perceived antenna issues, which did not materialize. For NVIS your antenna can be quite low, even a few feet off the ground. I have a 12m mast which could be used to make an inverted V on 160m. The SotaBeams wire is affordable and available in 100m spools... Maybe a 1.5:1 BALUN is in order, just to milk the transmitter to the max. My thinking is that if I was wrong about 80m being difficult to set up, maybe I am wrong about 160m. Or at least that it isn't as difficult as most operators say it is... Ray is the one who talked me into trying 80m, and he is right about the one-tank range being the most important. 2m SSB works well for that too, but I suspect 80m and 160m would be more reliable. 80m isn't the best during daytime, so I naturally wonder about 160m.

Too bad http://qrpkits.com isn't open now, because the Ft-Tut seems like a great rig. There is the 1-Watter on 160m, but I'd rather have 5W. If the Ft-Tut doesn't come back, I might go for the 1-Watter, or something else. Now if a few people inquired about the Ft-Tut to http://qrpkits.com, that might help, because the owner isn't sure about bringing it back... You guys know what to do!

I agree. I might still need to scratch that itch though, just as an experiment...

Quite right I'm afraid, though a very thin wire can be used. 80m works wonders though so most people have no reason to try 160...

A QCX for 160 meters :) Could you imagine how many turns you would need to put on T1?

LOL, 80m was hard enough!
