That would probably be HH2AA. Sometimes those remote stations stutter with their dots.

GREAT comments!

QRP – Like you, Joel, I would strain for most of the JA’s running “005” but every now and then, one of them would roar in here running the same power followed by one you strain for and he is sending “599KW”.  Amazing hobby we have here.  Ran some but don’t have the BIG station to get long one’s going, but I did have some surprises; HS2AA, 9J2BO called in and then disappeared, hi.

I went single band last fall for CQ WW CW and I think condx might have been a bit better then than this past weekend on 40.  Modest score for me, only about 12 hours total with 278/76.

Nick,

Tnx info on the K3!! I'm going to put a copy of this in my K3 manual in case I ever experience a similar situation!

Well, that's amazing. I worked 40 countries and I sure wasn't QRP or battery powered. When I see that gas gauge on DXHeat pointing toward the 'E', I figure: Not a good day for QRP.

Heard a few Arkies in there - ZN, SJ, N5EE up here in NWA. My best daytime band was 15, oddly enough.

After a "masked visit" from our daughter and family on Sunday I thought I'd try working a few more. But my K3 conked out! First, the K3 paddle input had no effect. Then it came back but the display said "ERR 12V" and it switched to 5 W. After that it said "CHK BREAKER" so I figured, I'm done. I'll have to send this complex beast back to Elecraft.  Maybe tell them to keep it and send me a K-4.

But later I decided to take the lid off and have a look. The breaker in the 100 W PA has push-on automotive type connectors (lugs). I pulled them off and checked continuity and the breaker was fine and not tripped. With one of the two lugs, the insulation around the crimp area was brittle and cracked off when I grabbed it with a needle nose. I looked and the conductor entering the barrel had black residue and there was also residue on an adjacent toroid. So I checked resistance through that connection and it was over 10 ohms. Ha!

I replaced the lug and got back in business. It brought back something I learned in my many years in nuclear power: Everything fails.  Even when quality control is excellent. Not every individual item of course, but every type of component. And they sometimes fail in new and surprising ways. 

So I'm proud to have fixed my K3 myself but also glad that it puts out useful error messages when something goes wrong.

I decided to try another "9 volt battery" effort in the ARRL CW DX contest with my little red rig - the LNR MTR-4b v2.  I grabbed a 9V battery off the desk that had been used for something else but measured a bit over 9 volts.  I operated about 2 hours.  Power at the beginning was 1.2 watts and by the end, voltage was 7.7 and power output was 700 milliwatts.  I stayed mainly on 20 meters and found that many DX stations answered me on the first call. Some required several calls and a very few couldn't copy me at all.  I was surprised that it worked so well since I was down an average of 30 db from a kw station.

I worked 50 stations, 47 on 20 meters, and 3 on 40.  I had 23 multipliers on 20 meters and 3 on 40.  I think one on 40 was not duplicated on 20, so that was actually 24 countries worked and that didn't count the US or Canada. 

The little MTR-4b v2 is an amazing rig.  With 12 volts, it will output 5 watts, CW only.  It has a built-in voltmeter, SWR meter, and wattmeter.  It's not like operating a "big rig" but it is just a little bigger than a pack of cards.  I'll be taking it out to the park when the weather gets a little better.

73,
Dennis
