Re: [Elecraft] QRP RTTY

To follow up: Many messages, both on and off list, indicated I should give RTTY a good try during field day. My results this year were a total of 201 digital QSOs with 21 RTTY QSOs. I had 3 dups between RTTY and PSK. (RUMPed seems to consider RTTY PSK separate modes and I didn't manually

Re: [Elecraft] QRP RTTY

Jim is right about this one. However, there was a huge gap between the RTTY world and the PSK world and it wasn't the technical differences in the modes. On field day you expect to find all levels of experience, from the seasoned contest op to someone using a radio for the first time in a

Re: [Elecraft] QRP RTTY

Indeed, QRP RTTY is quite possible. I worked ER5LL (Moldova) back in October of 2012 via RTTY. And, it was on 40 meters, at night, using an indoor AlexLoop antenna, running 3 watts. True, it was during a contest, but nevertheless, a QSO is a QSO. Pretty cool! And, I was using -just-

Re: [Elecraft] QRP RTTY

When the bands are open, you can work DX with QRP RTTY, though of course the S/N isn't as good as with CW. One field day I made about a dozen RTTY contacts in half an hour using FSK-D mode and 5 W. I had a long random wire up in a tree (probably 80' or so), plus a few radials. Wayne N6KR On

[Elecraft] QRP RTTY

Last year during field day, I made 186 PSK contacts and 1 RTTY contact running QRP. I tried for many more RTTY contacts, but in all but one case, the other station could not hear me. The one exception was on 10 meters with a station across San Francisco bay from our operation and probably line

Re: [Elecraft] QRP RTTY

I have worked FT5ZM in 21RTTY with KX3 5W from JA. Of course, pileup was very light then. When condition is very good and noise level is low at the other location, QRP RTTY is very possible. 73 de JH3SIF, Keith 2015/06/23 5:52、Bill Frantz fra...@pwpconsult.com のメール： Last year during field

Can't resist the brag... My best qrp is VK2KM on 20 meter RTTY Long Path with one watt (he has an amazing yagi), but the prize so far should go to WA2DKJ who worked C6 (1100+ miles from Northern NJ) on CW with his K2 at 1 milliwatt, using calibrated attenuators and measured with an HP power

Re: [Elecraft] QRP with the KX3

Excellent! And it will just keep getting better as you get more used to QRP operation. In Summer 2012, I was out back dabbling around using the KX3 at 100 mW CW on a dipole at 30 feet, calling CQ on and off at 10106 KHz. Heard a weak signal reply, and cranked up the AF gain into the headphones.
