General Discussion / Pacific Antenna, qrpkits.com, what's going on?
« on: June 28, 2018, 06:13:04 AM »
Hello,

Anyone knows? This is the ex Hendricks kits website at http://qrpkits.com.
All the prices and Buy buttons have been taken out.
I wanted to buy an FT-Tuthill 160m CW Transceiver.
Very concerning... I emailed them, waiting for an answer...

Can anyone suggest another 160m CW transceiver kit?

Gil.

Antennas / Re: Linked Dipole

Now I use RG-316. It is stronger than RG-174 but not as flexible. I have no idea about the losses. With RG-174 and RG-316 I avoid lengths over 10m, and try to stay on the lower bands. For the antenna on my roof (80010P), I use 10m of RG-58 plus 10m of RG-316, LOL. Even with only 3-4W on 80m I have no problem making tons of contacts. If you really want extra-low losses, try LMR-240UF. I personally don't care much, just try to keep it short and prefer 10mHz and below... RG-174 after a while will break...

Never but yes, I would like one too!

General Discussion / Ham Radio on Z-Nation.
« on: June 25, 2018, 03:53:22 PM »
Hi, ever heard of Z Nation? It's a parody of a zombie series. It's funny and you get attached to the characters; not to be taken seriously. Radio is featured very often, including Ham radio. Of course, they are very liberal with what radio can do and calling a fast food interphone from a satellite isn't an issue, but it has the merit of showing some kind of radio operations after an SHTF situation, be it a zombie apocalypse...

If you get bored one evening give it a try. The first few episodes aren't good, but it gets better...


The trailer looks much more serious than it actually is, though season one tries to be serious. I think they gave up on that later... After all it is coming from the same people who made Sharknado... It is full of references, to other movies, politics, religion, even history. I am sure I didn't catch them all! Anyway, just something fun to watch that doesn't require too much thinking and has radio ops in it...

Have you seen it?

There are a few radios I want to buy at the moment...

  • The uBitX, why not...
  • Weber MTR4b.
  • MFJ-9402X.
  • RT-351, brand new!
  • VRM-5080.

I have 110 items on my eBay Watch List, LOL.

Check this out, and have your wallet ready......

You f--ker, LOL! Well done.

Maybe I should get a similar case for my BitX40 still in its plastic box and not spend $100, but if I get some extra $ why not...

You just might make me spend my money Andy, tempting...

New To Radio / Re: New to HAM Community What is a good beginner rig?
« on: June 19, 2018, 05:05:49 AM »
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...

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?
