Ernie. I haven't played with the radio for over two weeks. (I know, it's a real problem, but)...
Just downloaded the newest release of 1.18.1 with no trouble. Seems to work great. I listen to a lot of shortwave radio in the AM mode and found the reception to be kind of noisy. So I remembered reading something about this problem, found your message here, and fired up my older 1.16 version. THAT version sounds quite a bit better on shortwave than 18 does. Don't have a signal generator over here, but the differences are obvious. I'm confident the folks will fix the code that's causing this problem. In the meantime, I'll either use v 1.16, or my Perseus SDR. Both of those work nicely! Best regards; -Tim ________________________ Hi all, First let me say I am enjoying my Flex radio greatly. It has been a true pleasure to be a part of this exciting evolution of radio. I would like some help understanding a phenomenon I am seeing that just started with version 1.18.0. After reading what Frank, WA3JBT posted about the AGC on strong AM stations and doing some testing of my own, I am noticing the same effect that he is; that is noise floor coming up in between words. I was able to duplicate this using a local BC station. I then did further testing with a signal source and the issue becomes very apparent. If I put an unmodulated carrier from my service monitor into the radio at -70dBm, there is some noise, as would be expected. As I increase the signal level, at some point I would expect the receiver to quiet. It never does, in fact the white noise I hear continues to increase with the signal level! If I go back to version 1.16.0, the receiver fully quiets at around -30dBm. Version 1.16 is more pleasant to use on strong AM signals than the latest code! Can anyone else verify this please? I have submitted a bug report but haven't heard anything back yet so figured I would post it here. (FWIW, version 1.18.1 trunk behaves the same as 1.18.0) Hardware Flex-1000/Edirol FA-66 PowerSDR version: various Thanks Ernie W2FMU _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/
