Today I enjoyed very much logged two QSOs with 4L1WL and HA6OD on 14060. I've used Micro-80/4 DC tcvr. Four bands VXO 3560, 7030, 10116, 14060 +/-, only 4 transistors inside, only 80 mW output, hehe. My antenna is 20 m GP
The best QRB is GM4YLN/qrp with 80 mW - 2760 km so far

Congratulations Oleg!
73/72,

well done , makes it all worth while .. you just wouldn't get the same buzz with 10 watts plus
-
Congratulations for for your FB QRPp accomplishments.

What do you use for an antenna and what is the secret of your success?

Hi ALL, thanks for replies. My antenna is 20 m GP including 3 counterpoise, heigh 6 m AGL (see the picture). Other antenna is "Up and Outer", 10 m wire wounded on 8 m fishing pole + one 10 m counterpoise, heigh 2m AGL only. It works good enough on 40 and 30 m bands with homebrew L-tuner.
About success... I don't know. I love the simplest radios and... God help me, sure :-) See my QRP results in top lists here - www.club72.su (http://www.club72.su) You can see that my humble results not so good in relation to results of OK1DPM, JA1KGW, GM3OXX etc.

I'd like to note, I agree with Mark LU6DO. If you love QRP (QRPp) and save patience - success will be with you! Remind:
- op. Angel LZ1SM (SK) became "QRP Master" using only homebrew 1-2 transistors xtal TXs on 14060 kHz only!!! Less than 1 watt!!!
- op. George GM3OXX have great results using only homebrew tcvrs not more than 1 watt (over all his life!)
- op. Mike AA1TJ (present here) always used simpliest milliwatting to wire antenna. There are few trans Atlantic QSOs in his log.
I take off my hat before above friends.
Finally, enjoy picture with my cats (Mark, do you like it?) Cats want to say "Finish your K2 and lay down together, have a rest" :^)

So just keep trying if I understand you. I have had some success with a 1 tuber using a 50L6 with crystal control on CW. It is on 80M with an inverted L. I also have had a report with my two tuber transceiver although didn't sound like it was appreciated but it was definately heard. I have several hb rigs around 5 watts or less, Sometimes it seems fruitless. What time is best and what bands and where on those bands? I have been working 7118 today with two of my rigs , the TNT and the two tuber , both CW and AM. My main activity is AM on the weekends on 80M with dx60b and a homebrew 811A amp but that is social thing. My real interest is in low power rigs as they were in the 20s and 30s as well I have a crystal controlled three transistor unit I built for 80M many years ago. Just under a watt output but a good working tx. Perhaps it is time to dust it off. Any tips would be appreciated

Don, thanks for interesting dialog. I love valves radios also. That was my youth. Today, I became lazy to drill and saw the metal, hihi. Maybe, the GlowBugs will be my next song.
Who interesting for simpliest 1-2 transistors TX? Put your eyes here - www.club72.su/vanguard.html (http://www.club72.su/vanguard.html)
In March-April some "almost crazy" friends played the game named "Vanguard-1 QRPp Party devoted to 55'th anniversary of the USA satellite "Vanguard-1" launch. On the page you can see pictures and schemes of QRPpp TXs less than 100 mW. There also a totals log-book of QSOs on 18...100 mW power. Me, I used TX on GT320b Ge p-n-p transistor 30 mW. But only skimmers (RBNs) copied my sugnal, sorry.

drill and saw the metal,
PSSSSSSSSSSST
I make all mine on wood. No shock hazard. no hand effect etc etc.

Hi Oleg! I deleted my post by mistake, but fortunately I found your comments here.
Amazing photo of the cat!
Mine does only hunting small mice. It will be under the influence of QRP? :)

Congratulations on your accomplishment!! 72/73 John N2DVD

Kamon Oleg! Congratulations, 80mw? Amazing...
I used 500mw and QSO with all the world on JT65, to much distance also in CW, of course :)
Best 72
