Re: SR40 noise and spurs
I also have a 2 Khz wide unusable portion at the center of the passband. Mine is 30 db above the baseline, and the shape and bandwidth of the spike changes as I tune across the center frequency. I

Re: Rocky
Very nice, Alex. Considering the quality and innovative software you are known for, Rocky is a winner. My only suggestion is a wider filter esp. since 40m is such a hodge podge of adjacent

Re: Software for SR40
Thanks. Cecil Bayona KD5NWA www.qrpradio.com I fail to see why doing the same thing over and over and getting the same results every time is insanity: I've almost proved it isn't; only a few more

Re: Software for SR40
Try this also; Go in the control panel and run the "Sound and Audio Devices" Make sure all the voice and music devices are the sound card you want.

Re: Rocky
Rocky looks really nice. Started up perfectly, and controls are very easy to understand. Now I just need my Softrock40, so i can get some sound out of this software. Guess I???m among the last on

Rocky and soundcards
I apologize for the problems that Rocky has with some soundcard types. The WDM audio interface is poorly documented, and I had to do some trial and error work to make the code open my Delta44. Other

SR40 noise and spurs
Hello all. Had noise and zero spur (DC...) that were wide and strong (rendered a swat of 2 khz not usable around the LO freq.) Saw among the photos what N1RX did with a battery driven SR40

Re: Software for SR40
I had the same problem with the "Rocky" software, and after I installed ASIO4ALL and made it the audio driver, the error then went away. I was using a different sound card, a SB Live 24. You can try

SR40 noise and spurs
Has anyone tried using surface mount components vs pin-in-hole to see if there is any reduction in the above ? I'm using the external PS and will try surface mount in a few days. 73 Kees K5BCQ

Re: wide range tuned input circuit
Check out Yaesu FT101 parts on e-Bay. Just purchased a PT preselector for $12. The Drake R4-B/C also had a PT front end but parts are scarce and expensive. I've seen similar at Fair Radio. Dick
