The 817 is at the limit. I like it, it's an excellent radio. Actually, if I had 600 Euros now I would probably buy one... Especially that it has 2m and 70cm SSB. Make a portable 2m Yagi like I did and you'll have a lot of fun!

considering that there could be a grid down and most of the hams are out of order and the air is much cleaner?

Oh yes! I bet most amateur stations will be down the minute the power goes down. Some will stay on the air a bit longer, 2-3 days, maybe even a week. After that, it's only going to be small CW rigs and a handful of people with big solar panels.

If you watch my latest video, posted yesterday, I make an easy contact on 80m using 3W out maybe, with eight AA batteries, and they last a long time. Add a solar panel and a charger, you're on the air for months, maybe years...

Nice, what band? CW?

id personally like the option to drop the power

Good point, I know of no small QRP rig with a low (lower!) power option... Great idea. It probably hasn't been implemented because of the extra circuitry. Often, dropping voltage will do the trick...

I was getting out to S. California on about 150mw.

That is amazing Joel. It really shows that sometimes it doesn't take much.

Thanks for your input guys.

Morse Code / The One-Watt Magic Number.
« on: June 15, 2018, 08:38:19 AM »
Hello,

Trying to make a contact again with my Pixie and maybe 300mW, I recalled most of my past QRP and QRPp attempts using CW. Usually, anything a Watt and above is no trouble at all with a full-size antenna. I even made a contact once from Florida to Estonia (5K miles) using 1.3W! Even my Rock-Mite on 40m seemed to work fine, though the issue was more of a receiving one, because of the lack of selectivity. Then we get down to 500mW, where contacts are still possible, just a bit harder. Below half a Watt things become very dicey, though I have tested 100mW successfully on more than one occasion with Ray 820 miles away. For calling CQ however, one Watt seems to be the practical limit. It gets better from there on up, of course, up to five Watts or so, after which adding power doesn't seem to do much more, at least when conditions are somewhat favorable.

This brings me again to the conclusion that QRP radio designers know their business. Aside from Pixies, Rock-Mites and such, which are fun novelties, great practical radios start at around two Watts. I especially like the SW+ series (ME+ now), and of course, the Weber MTR rigs for QRO operations  ;) I would love to see a surface-mount SW+! Instead of adding current-hungry features, what don't we make radios smaller? We have the technology with SMT components. There should be rigs out there the size of a small box of matches. The limiting factor should be the connectors and controls.

Anyway, just rambling... I think a practical radio should have a minimum of around 2-3W to be safe, with 5W being great. One Watt could get the job done but I would not count on it. Below one Watt you're just having fun, and that's great. BTW the 817 with a less than a full battery outputs 2.5W and people make plenty of contacts with those, even using SSB.

What do you think is the practical power threshold for a CW-mode survival radio?

I suggest not using words like "Mayday" or SOS in Morse... Even for a simulation, and even with a warning.

Morse code with flashlights! Then have them try to decode slow code on the radio...

I have had some luck on 80m and 2m USB... Otherwise it's 599-73, sad indeed.

Antennas / Re: Random wire antennas and tuners

Try a clamp-on toroid choke and slide it on the coax for best SWR...

You might want to try a different wire length for 40 and 80m. Also, try a different coax length and maybe a counterpoise. Random wires can be a pain, but they do allow multiple bands...

Sure won't do that again! :o

I knew it probably wasn't for me, but with all the hooplah, I had to give it a try, at least to know what I'm talking about if ever that conversation pops up in good company... I even made one contact. For me, it's like watching paint dry, utterly useless and uninteresting. I'm not bashing FT8 users or even FT8 here, but it just isn't for me, by a very long shot.

I used the same software however for WSPR, to see my antenna radiation pattern, very useful, got Venezuela on 40m 2W. Of course with WSPR you don't put anything in your log, but I couldn't care less about my log. I actually only input contacts maybe half the time, when I don't lose my notes, forget to write the date or call signs...

Radio for me is about human interaction if only to ask what antenna someone is using... A few words about the weather, even a simple FB, exchanged between two people, make my day.
