Hi Steve If you could listen out for me on normal cw, slowest speed about 4wpm. Give me a suitable time and freq on 136 khz and I will fire up in your direction. I have been heard out in your directi
Hi Alan and all, Yes, there is life out here too. Being 'on the fringe' I'm reluctant to have anyone burn electricity at my behest, but I will make an effort to have a rig driving Argo if anyone decl
Hi Ulrich, Concur Dave's advice on the Inrad filters. Their 125Hz @ 455kHz filter, although it might seem ridiculously narrow by 'normal' standards is perfect for LF use. In fact it's super for conve

Hi David, Sorry to miss such a likely successful opportunity for a transatlantic hit, but I'm going to be in, um, England. Cheers, Steve, W3EEE With 800 Watts and a 170 foot top fed vertical I hope t
Hi Mal, Got a couple of scruffy Argo's of you from tonight (Sat.) Heard you QRZing on 40, called you to no avail. A 4X came back to me instead, (yeah, yeah, yeah, 599001, TU). Oh, well . . . Not 'hea
Hi David, But remember the Ampliphase dates back to a time before the advent of a practical PWM modulator. Yes. The PWMs and latterly 'digital' modulation types put paid to the Amplis and Doherty's a
Hi David, and all, There have been a few 'wet' Amplis. Big L, probably the most 'pro' of the sixties pirates, had a 'G'. The most bizarre was probably the 100kW version on RNI's 'Mebo II', which had
Hi Zim, To be fair to TI, their intention is that these amplifiers be used in self-powered speakers, where the speaker wire length is inches (sorry, cems) at worst. For the last few weeks I've had a
Greetings, I find the best tool for sticking down fine-pitch parts is an intern. But that's cheating, really. There is one truly gruesome, cringe-worthy technique that I've used when pushed, and alwa
Greetings, Happy New Year to all, I went looking for info on this some time ago in order to bring some stability into my life and an old Eddystone. This place is a treasure trove of nearly everything
Hi Laurie, Not a hint, sorry. Cheers, Steve CFH is building up nicely here,so I will run some DFCW30 for about an hour on 135,921.5 Hz. If anyone is about T/A I should appreciate a report. 73s Laurie
Hi Andy, As a couple of the other guys have pointed out, it depends on the soundcard. Assuming it does have an onboard crystal or brick to determine samplerates, yes, of course one can take liberties
Hi all, Another proponent of the fishing-rod method. It does presuppose at least some wasted youth shivering on river-banks, or at least some patience as one learns how to cast. My favourite is a 7ft
Hi Alan, As far as I know the senders at Droitwich were Macaroni 'PULSAM's, their trendy name for PWM modulation, and installed some 20 years ago; these essentially are a whacking great class-D audio
Hi Alan, I'm afraid that the sigma-delta convertors which almost completely dominate the audio world nowadays don't have that aliasing 'feature', thankfully. Simplistically, they're a single-bit conv
Greetings, Firstly, may I add my heartiest congratulations on this 'Jason' first, to Jim, John and the conceivers and developers of the mode, especially Alberto. Quietly, in the hope of eventually tu
