Hello Stefan and Hugh, OK, thanks Stefan and Hugh, I don't think they had anything over about 18V secondaries. I got my toroidal transformer for my G3YXM 136kHz amp from www.tme.eu as they were the c
12 October 2015 I seem to be getting a signal out now that at last my station is on air, so any comments on the signal quality very welcome. I do have an ongoing but improving issue, but I will start
Hello DK7FC, Monday, October 12, 2015 Thank you all for the congratulations and reports. Very early days yet, and many improvements need making. The aerial is my HF horizontal quad wire loop, up abou
Hello John, Tuesday, October 13, 2015 I have no direct RF ground on the rig, as my shack is upstairs and I found on HF the long ground lead was radiating. I found much better results without a separa
13 October 2015 Got my (brave...) friend adjusting the variometer in real time whilst I talked to him by phone, and whilst transmitting at one setting below full power. I watched the `scope in the sh
Hello Alan, Tuesday, October 13, 2015 Thanks Alan, appreciated as always. I may be doing something wrong as I can't seem to get the phase right, I will try later when my pal is free again. When he tu
Hello Roman, Wednesday, October 14, 2015 Thank you very much Roman! :) It's far from optimal right now, but I have plans to improve things! Right now I am just fascinated by how far it gets "as is".
14 October 2015 If I mount my PA0RDT clone on my mast stub, about 50 feet from my LF TX'ing aerial, is it likely to be damaged if powered on when TX'ing? Thanks. -- Best regards, Chris mailto:chris@c
Hello Alan, Wednesday, October 14, 2015 Hi again Alan. Thanks for the info. I have got a better match by making a new tap on the loading coil between 2 existing ones and now the variometer will shift
Hello John, Friday, October 16, 2015 Ah, right, OK John, thanks for that. I may try a galvanically isolated matching transformer. I realised late last night that my wife's complaining of the workshop
Hello Alan, Friday, October 16, 2015 Things took a sorry turn late last night, when making a final TX I noticed the meter in the G3YXM amp that switches between FWD / REF and measuring DC volts was r
Hello Graham, Friday, October 16, 2015 I have found the Zobel network resistor (22 Ohms, 25W) badly overheated but not open. I also found one leg of one of the 4n7 caps on the primary of T1 the outpu
Hello Chris, Saturday, October 17, 2015 Too posh for us Midlanders and Northerners, we don't understand the dialect ;) -- Best regards, Chris mailto:[email protected]
17 October 2015 Ease of use a priority over "features", what should I be trying in order to TX a QRSS signal on my Windows 7 based PC please? Thanks. -- Best regards, Chris mailto:[email protected]
Hello Mal, Saturday, October 17, 2015 I should be OK to try this, I deliberately bought a modern motherboard with one true serial port, and it's also got PCI card with 4 more on it. So should be good
Hello Ulrich, Saturday, October 17, 2015 Thanks for the kind words and the link to the software, I will make up a serial lead and give it a go when I get chance, all the best Ulrich and all who repli
Hello Roman, Wednesday, October 14, 2015 You once asked for some photos and info on my HF aerial, which is now also my LF aerial :) I remembered to take some today and they are zipped up at: http://w
Hello Mike, Sunday, October 18, 2015 Major typo in my original post, the matching transformer was best tapped at, or one coil down from, the *LOADING* coil end, not the earthy send, sorry. I will ass
18 October 2015 I have a Scopematch box in circuit between LF amplifier and feeder co-ax, inside the shack. Does the current waveform simulate the same thing as a current meter? Or should a current m
