Hi, Verify the total DC Current. I remember about 85-90 mA from my unit when set at 100 mW output when it was in FSK CW mode (now CW). Is your RF cable OK and correct impedance (75 ohms can throw a

I built my first 30m beacon and it worked first time, but I have not been able to get the power out up to 100mW (20dBm). I only get about 54mW (17dBm) into a 50 ohm load. I measured this several ways

I have put a 5.6pF miniature ceramic in series with the 1.5-5pF that I used for C9. This gives me a frequency swing of 405Hz between 3500.720KHz and 3501.125Khz which makes tuning to the desired

..and have some questions: 1) Is there any particular reason why the 2N7000 was chosen over the VN10? The VN10 comes in a number of versions but the only significant difference I can see from the

Anyone built the Pongrance 30meter beacon rec kit? see http://www.pongrance.com/gcrx-14100.html At $35 it looks like a bargan. Paul k5wms

Has anyone on either group spotted Phil, W3HZZ on 10140040? Been on for 24 hours and no reports. I have looked at a number of grabbers, but cannot see W3HZZ. Thanks in advance, Ken

I'm not doing very well today :-( that should say 3500.900KHz not 7MHz. My latest 7MHz MEPT is under construction now to be followed by one for 30m in the next day or so. During off and on air

A friend, W3HZZ is now on 10.140.38 from Atlanta... Please let us know if spotted

Hi Ken I built an 80m kit today and had the same problem with the oscillator being too low. The only trimmer caps I had to hand wouldn't go low enough so I used a "gimmick" cap same as the

Hi Guys, The G0UPL beacon kits are available again. Please order them via the shop<http://www.hanssummers.com/shop> on Hans's website. Please do not forget to tell us the callsign you want programmed

There has been a bit of chatter about 80 meters. So, I am tonight, I am on 3500.828 at 70 mW. Are there any 80 meter grabbers? What is the url? Ken Evans, W4DU QRP ARCI 696, GQRP 5918, FP 295,

Arv, I visited your page to read up on the receiver. I am a novice when it comes to theory and such, so it is helpful to read your notes in detail. You mention the use of FT36-43 toroids as cores

Hello A new QRSS receiver and new QRSS grabber are now on-line. Details of the receiver are available here <http://qrp.webhop.net/QRSS_Receiver%28K7HKL%29.html> and the grabber output is

Hi guys, First of all may i apologise to those of you who have found a couple of parts missing in recent kits. I have a very small brain and sometimes I loose count when I get distracted. If you do

Thanks for the information guys Very useful... Regards Philip

Hi Hans, Philip, fellow QRSS knights, OE1FM has designed and built stand alone beacons that are running in Africa (V53ARC that I seldom receive). Design is a bit complex but perhaps some idea could

Hi Philip It could, but not easily! Well, depends how you look at it. If you just look at the board as a plain 30m transmitter, and then decide to interface it to your PC, and have the PC generate

Out of interest, could one of these TX boards be used/modified for use as a WSPR transmitter? Regards Philip
