Since you are now in full swing chasing faulty transmitters and know the procedures have a bash at sorting out loran and rte, there is no point in anyone else re inventing the wheel. GO FOR IT John.
That just leaves us with the 'Ugly' .... ! You using the main ae for rx ? perhaps a small loop would be better ? Yes, and normally this is no problem (a 20dB attenuator takes care of all IM problems)
It is indeed like lottery for those with no knowledge. And in that case the chance of succeeding the test is about the same as the chance of winning the lottery. In a well designed MC test the chance
An amateur radio license is much more than just a transmitting license. In most cases it permits the holder to experiment, build his own equipment etc ... This in contradiction to most other transmit
Mal, I never had any trouble driving 2 x 2 Hi power FETS 75n100 with a TC4426 on 137 khz. Power around 1Kw input. On 137kHz the TC4426 works fine. On 500kHz it works pretty good when driving 2 single
John, it's going to be a busy weekend but I'll try to be QRV in the evenings. I just made it to your grabber running 20W output (0.2W ERP). The signal looks still fine, but that's as low as I can get
6m better with UT3UA and ES0NW worked all on CW. De G3IKEV What is the point about all this 50MHz reports? 1. What is the relation with 137 or 500 kHz 2. What is so exceptional? During the Es season
Dear all, Quoting [email protected]: As far as I know commercial morse services never tried to use the morse code for printing. That's true. But if we (radioamateurs) never had gone beyon
Dear all, last night I did some first test on 500kHz after my "summer recess". Good: I found out that my digging over the past months had some success, the antenna current is up with 10% (now 2.2A).
Based on the antenna description given by Mal ("1/4 wave inv L for 500 khz, 100 ft vertical and rest horizontal") simulation reveals a radiation resistance of 5 Ohm and a directivity of 1.5 dBd. This
Dear all, experimenting with my actual 500kHz/300W PA I found out that the popular TC4426 driver has trouble to switch a couple of IRFP350's properly at 500kHz. For that reason I intend to build a ne
Stewart, an alternative to penalty points for wrong answers is increasing the minimum score required to succeed. Maybe they do that ? If not (thus 50% = passed) it besomes indeed a gambling game. 73,
a better (non google) translation would be : excuses are made to be used 73, Rik google french to english gives apologies were made to use but thats google 4u hihi G .. -- From: "Rik Strobbe" <rik.st
Scott, first thing to find out is wether the interference comes from the mains or from the power supply. Switched PSU's can be horror. Can you use another power supply, if possible a good old fashion
Hello Brian, good to have another grabber, thanks for the effort. Due to rain and wind I couldn't transmit last night, but I will give it a try as soon as the weather allows. 73, Rik ON7YD - OR7T htt
Jim, group, I didn't notice the QSO as it was after bedtime ;-) But on several occasions I have noticed that in the early evening (18-20UT) the VVV signal is weaker than DI2AM while later on it becom
I saw "FMT" in QRS earlier tonight, was that you ? The signal was very weak audible. QRN was rather bad (and going worse over the evening), with low QRN a QSO should be possible. 73, Rik ON7YD - OR7T
Propagation seems to be good tonight (and QRN low). I just worked G3KEV (589/589) and SM6BHZ is 579 on 504.5 (beaconing). I will stay QRV till 21 UT, mainly listening on while doing some other things
I can hear very weak CW just on 502.0 kHz. But due to strong QRN I cannot get a call. 73, Rik ON7YD - OR7T PS: Finbar is 539 here Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm
Mal, when time permits I will try to be QRV during the day on saturday/sunday. 73, Rik ON7YD - OR7T Propagation seems to be good tonight (and QRN low). I just worked G3KEV (589/589) and SM6BHZ is 579
