Dear all, I just started a QRSS10 beacon on 503.7kHz (right now 503.705 but it might drift down some Hz over the next hours). The beacon will start every 15 minutes at +6 minutes (so xx:06, xx:21, xx
ONLY 3 IN THE WHOLE WORLD!!!!!! Actually 3, Mal, but we are not allowed to work DX... As far as I know there are only 2 active amateur radio stations on both LF/MF using CW G3KEV and G3XIZ I am now
How many UK stations are running the current 10 W ERP limit ? Since the increase from 1W to 10W I have noticed only 1 station that became 10dB stronger. I have made QSO's with UK stations running as
Petr, you can use a Pi filter, but I am afraid that the values might become rather inconvenient: A short (relative to the wavelength) wire antenna will act as a R-C series circuit where C is the ante
If anyone wants to use one of these slots I will stop the QRSS transmission 73, Rik ON7YD Andy, No one will be able to use red-2, green-2 or blue-2 as Rik OR7T is sending his call sign QRS starting i
Aha, that was the strong and strange sound at the upper band edge ;-) I was already preparing for another hunt for a bad energy saving lamp or switched PSU before I noticed it was a real signal. Ther
And, by the way, the "sphere in sphere" variometer has a big drawback: Its Q is quite OK at maximum inductivity but very poor at its minumum. Explanation is simple. Just assuming the resistance of th
Graham, I just noticed the signal while doing other things in the shack. But I will have a look at http://groups.google.com/group/uk500khz/web/zl2afp-psk-sounder and find out what I need to participa
Hello Mike, I am using a "clone" of the M0BMU design. It is a 4MHz ceramic resonator VXO, divided by 8 to get 500kHz. It tunes the entire 501-504 band (in fact 500-505) and after some warming up it i
Gus, the signal was remarkable strong, speaker copy. You were taking to another SM station, so I could just understand a few words ;-) Last night I heard you in CW QSO with Finbar, both 589. Eu propa
Dave, good to hear a new call on 500. I had a lot of other things to do, so couldn't stay in the shack and give you a call. But the signal was good, a QSO should be possible day and night. 73, Rik ON
Gus, 55 with some QSB on JO20IX 73, Rik ON7YD LF group, I will be able for X-Band QSO on SSB (USB) after 20:00 Z this evening. QRG 505,5 kHz to 7043 mHz +- QRM both USB. 73 de Gus SM6BHZ Disclaimer:
Gary, before going to sleep I re-tuned the VXO to about 10Hz down from Andy's signal. Based on last night's observations it will shift up 20-30Hz over the night (due to temperature drop in the shack)
Dear all, last night I worked Graham in THROBX2 mode and a bit later in PSK31. Under the given conditions (lot of QRN and QSB) THROBX performed better than PSK31. MFSK4 seems far inferior (at least h

Gary, good copy now: oklee ..slight slip .. but all back ok .. fine on the tx , well 160 should give a good signal , ok on the pic , yes wire it over iedta [email protected] after the gb4fpr night of cw
Still, Hiroshi's transmitting on 136.9 CW and Ive left my grabber on there on slow speed to see if I can detect anything after dusk tonight - its a +-2000Kms all water path save Korea and a bumpy bit
Hello Gary, call the is almost right, locator completely. But not really impressive for 500mW ERP. I could see my signal on your grabber, some slow QSB but strong for the last 2 minutes or so. I used
Dear all, I will do some FM-Hell transmissions tonight on 503.5kHz from 20:30 UTC til 21:20 UTC starting every 10 minutes. Between transmissions I will "listen" on the same frequency. Report are welc
