/sm6pxj I would also like to join you all. Though the vfo is stable, I checked overnight against the existing transmissions, it has only 1Hz setting resolution. 73, Brian 73 Brian CT1DRP IN51QD 41 09
To all, Last night I returned to monitoring the 136 band and CFH. At 0500 the signal was -55dBm and at 0700 was -53dBm in 20 Hz on 137.040KHz. The dawn noise reduction is there as usual. As discussed
Gentlemen, After careful calibration of the sampling rate using HP signal generator and WWV on 5MHz AM which gave the same value, also checking the stability and absolute frequency accuracy of the re
Walter I will be very pleased to have a qso but I am afraid that I "crash out" about 2100utc. I do wake early if that is any use but otherwise during the day. Let me know a time, 137.695 seems ok and
I'm sorry, I could not resist. 73, Brian The tube was used for HF- and wideband-amplification up to 50MHz. The amplification could be regulated by varying the negative voltage at grid 3 - says the bo
Andy and Tracey, possibly others, C1,4,11 are all marked as 1 not 0u1 on both the cd and the components list. The only difference is that 1 is a polyester 100v whereas 4 and 11 are ceramics 50v. Unfo
Gentlemen, Can anyone point me in the direction of a RA1792 tech manual/circuit diagrams and more specifically a 1uF 50v ceramic capacitor, radial leads about 0.3in spacing. 73, Brian 73 Brian CT1DRP
Hi Larry, If the WOLF transmissions are not going to be readable in Europe we have the option to change the time, or add another hour at a different time, or the digital session can be ended if it is
I hope to run a WOLF - mode signal this evening from about 2000utc. I will start at 300mW ERP, then after an hour reduce to 30mW ERP and leave it running for a couple of hours. As before, I will tran
Hi Valerio, I made a recording of 30 mins between 2030 and 2100 and although there seemed to be some sort of lock which gave repeated data the decode was not correct. 73, Brian I made 3 recordings of
Gentlemen, The band has been superbly quiet all day since the street lights went off this morning. There are a superb set of loran lines on my wideband recording, both the signal on 136 and DCF39 hav

Did someone transmit in the 135.920KHz slot last night between 2300 and 2304utc? 73, Brian 73 Brian CT1DRP IN51QD 41 09 58N 08 39 11W http://homepage.esoterica.pt/~brian
Laurie, I may have found a better way of creating the page and have loaded it but only your page for the moment. Let me know if you succeed viewing it. 73, Brian At 19:22 22/05/01 +0100, you wrote: B

May I add a request please, I am looking for the design of an "ultimate" 3dB splitter for 136KHz with good characteristics to well down below 72KHz. 73, Brian First the antefact : I swapped recently
