I have this QRO-amplifier for sale but because of the weight and size, only local pickup is possible.
Think ít´s only interesting for amateurs located in Sweden.
It is advertised on:

Ray,
How discouraging, I've been waiting until the price on LED light
bulbs is more competitive, to buy some to replace my
incandescents. I refuse to succumb to the CFL hype, besides they
don't put out enough light (lumens), and also they don't seem to last
as long as the incandescents. My line voltage is a bit high.
Before my hearing deteriorated i could hear an audible noise from the
CFLs, and experienced an increase in RF noise with them.
73 & keep up the research.

Hello all,
I have a new PC Linux: Ubuntu 11.10. Type 64-bit OS.
I fail to install WSJT.
Does someone could help me and give me the complete file compressed to
successfully install WSJT?
I downloaded the file on the site K1JT, but I do not know how.
I also downloaded WSJT in the Ubuntu logitech but I not work.
Thank you for your help

For sale a Thomcast 3 Phase power supply 3x 400V AC input (needs 3 phase
and Ground NO Neutral)
Output 50V DC 120Amp continuous for a serious mosfet amplifier ;-)
This supply was used in a broadcast amplifier, it was feeding 2 pallet
amplifiers of 1.8KW each
Asking 150 Euro
I have NO documentation available..
Prefer Pick-up because of it's weight.
For further questions or photo's you can drop me a mail.

I work the LF bands, in particular, 137 & 183 KHz weak signal as well as
just getting started in EME. I recently replaced all of the 48 inch
fluorescent tubes (8) in my shack. The new ones are noisy ... the old ones
were not. I decided to try a couple of 40 watt replacement LED bulbs from
Lowes.(they draw 6.5 watts). I don't think that they give off quite as much
light as a 40W incandescent bulb but they are close. They do give off a
whiter, perhaps cooler light. I've been using them for about a year. I
notice no noise from them what so ever. I hear nothing on the LF bands
(where just about anything is noisy) or on 144 MHz. They were on special for
about $15 and I was thinking about replacing each set of fluorescents with 3
of these bulbs. I will take a real close listen before I do this ... but so
far my experience was been very good.

Hello Weak signal listeners ,Moon Bouncers, and SW listeners
Again I went to the big box store to buy another brand of LED light, This one is by Sylvania, it is a 8 watt unit to replace a standard 40 watt 115 v lamp......If you read the specs it will do anything....Last forever, Dim-able, consume no energy, etc..... BUT
BUT..........again this lamp is a big noise source, I did not even have to bring the test probe to it, for it to be evident....as soon as I screwed it into the socket the noise level on 50 went up 2 "S" units........I did some probing and the noise is going back down the power line.....Yes the Diode noise is very loud with a probe near the lamp but this one distributes it to your electrical system.
This is my third try and I did find some 4 watt lamps that I wrote about on last post that are quiet, not even diode noise at the glass distance.....so I know it can be done,
