Hi Andy Bill moved west but did appear on one of the groups a few months back I think. I seem to remember Toronto being mentioned. The progress was COHERENT>> AFRICA >> AFRICAM. I think, Wolf appe

Consider using a Tee input low-pass filter, so the PA sees a series inductor first, rather than a shunt C A shunt C input will give large current spikes when hit with the square wave from a voltage m
Yes, I had that once. Surreal, isn't it ;-) 'jnt On 2 March 2016 at 12:17, Paul Nicholson <[email protected]> wrote: I just discovered something as I turned off the 12V supply to the CD4040 I've be
Forging is pretty impossible. You'd have to synthesize the address and as thersgb.net no longer exists it can't be done. The other option, unsubscribing an alternative email address needs moderator
Can you transmit DSB? LSB = WOLF-whatever-speed USB = WSPR-15 That would be interesting! 73 steve G3XKR Sent from my Xperia tablet -- Andy Talbot [email protected] [rsgb_lf_group] wrote --
What is needed, is a software package that runs in parallel, monitoring and recoding the noise level. It would have to work in a manner that was unaffected by the presence of signals, and also on a
Dear all, I have set up a small website about the 472 kHz band. The goal is: - For newbie's: to provide some basic information about this band, in the hope that this will attact "fresh blood". - F
Is that to minimise skin loss in steel track ? UK Third rail is, of course, DC, and I once spent an idle moment calculating the loss if 50Hz AC were to be used with magnetic iron conductors. I think
Dear all, at the next IARU Regon I Interim Meeting (Vienna, 16-17 April 2016) there is a proposal that concerns the 630 m band: It is recommended that beacons will be accepted in the plan of u
Andy, This time its not really Stefan's fault :-,) This is a problem , using the raspberry PI , the Pi processor uses interrupts, which, cause the execution time of the timing loops
Hello all, I've been watching the 100Hz sideband WSPR multi-decodes also from the other two strong stations on MW, DH5RAE and DB0ABR.They are located about 65km from me and generate S9++dB signals
The auto-translate button at the top makes for an interesting result : "Hello Paul, thank you, I am me through this connection and congratulate you on your performance. Because the evidence could on

I know the subject is nothing to do with LF, but I didn't keep the original thread... A few months ago someone on one of these two LF reflectors pointed me at the Enhanced USART in the 16F688 and lat
The pointer I had came from Johan who listed the PIC code to get 3MBaud from the PIC's EUSART. And I've just been trying this on a 16F688 only to find the PIC itself is doing something odd and se
That seems a very convoluted (!!) way of doing what is actually quite a simple process. Input low-pass filter, I/Q mix with a centre tone, low pass filter the output- and there's the baseband signal
It's not a Weaver modulator, but G3PLX's SDR transmitter that generates I/Q outputs from a soundcard and also, in a very clever way, allows FM and AM to be generated when no DC component is present.
