To save long-winded explanations, I have drawn a circuit diagram of my modified version of the G0MRF PA output circuit, with some details of the output transformer. It is too big to send via the PSE
Hello the list! I am still RX QRV with the new front head high Z adaptater ( a pair of BF988) on the 2 meter's loop. I will be very happy to receive somebody with this equipment... Any station ready
Will make an attempt this evening, if you like - I can be QRV after about 1800utc if that is any good, Cheers, Jim Moritz 73 de M0BMU OK Jim. I go no air after 1800 utc, 137.700 +- 20 Hz, QRSS 3 sec.
Thanks to Jean-Louis for the report - I have been transmitting occasional CQ's since about 1800utc - I saw a weak signal at about 2020utc that I am fairly sure was IK2PII, and sent an "M" report - ho
Hello all LF'er I am very sorry but not internet ( and no phone too) from my side during last day. Someting wrong somewhere in a wire... (grrrr!) Now it's ok! ... (only 302 meesages) :0) For Peter DJ
Hello Claudio, The noise is quite good the evening, are you OK for a test in QRSS3 or 10? Sorry. I'm reading the mail only now. I try transmit this evening after 18.30 UTC, QRSS 3 sec, 137.700 +- 20
P.S for the RX builders Order code 12-0274 is the GEC-Plessey SL6440 high performance mixer, mis-described as a "complete radio IF chip". These are very good performance double balanced mixers (Gilb

Hi Mike and Uwe! Received in Milano, with loop antenna in balcony and direct conversion receiver, despite Xmas lights. 23.00 DJ8WX O signal, 20 dB over noise, increasing to 30 dB over noise after 00

Ah, but have you ever dropped a soldering iron and instinctively grabbed it as it fell? I doubt if I am the only person to have been burnt in this way. No, you aren't alone. But I'm grabbed the solde
Getting back to the FT-817, is it possible to modify the front end or first mixer so that a preamp would be unnecessary? Many RTX uses inexpensive diodes in the front-end design, for bandpass filter
I know about GLFER. But it uses X-window subsystem (someone very similar to MS Windows interface) wich is too resource hangry, not adequate for my old machine. Look here: http://www.damnsmalllinux.or
Why one need 24-bit? Though 16 bit is adequate for most SW,MW,LW recievers. 16 bit yelds abt 90 dB dynamic range (every bit exept sign bit yelds 6dB). This means that 1 bit give a sufficient MDS? The
Hallo Dick! It's not a PLL it's a conversion VXO using two easy to buy xtals. The schematic is on my web - see signature 73 de Claudio, IK2PII -- Claudio Pozzi - Happy Linux User - http://www.qsl.net

Hi EA4BVZ Received in Milano, JN45OM, at 22.00 UTC, about 20 dB over noise. Antenna: miniwhip like (my own project) on balcony 6th floor east side of the building RX: direct conversion SW: SpectrumLa
Hallo group! I'm testing an E-field antenna, like MiniWhip, but DC coupled for RadioNature use, down to few hundred's Hz, and up to VHF. I've found that I have a lot of noise reduction if the antenna
20 - 25 dB less than power out 200 kW. So 2 kW and a giant antenna are good for QRSS QSO at 17 kHz in Europe ;-) We should ask to borrow SAQ antenna and try below 9 kHz, in the unassigned band ;-) I'
