That's very good to hear, Alf. Sure wish the 5000 had a noise figure that good on 6 meters. Sadly, it doesn't and requires a pace maker (preamp) and some care to get to that level.

It is really great to see the activity pop up on the panadaptor, and also see (and avoid) the birdies and general crud that is the bane of operating 6m in an urban area. I was worried that I may not have enough sensitivity, based on comments received from those running the F5000, but I really don't have an issue with that. Going from a good 50ohm termination to the actual antenna, a 6M7JHV at 60ft, I see between 10 and 15dB increase in noise level depending on direction. Adding an external preamp would not give any benefit in my case, although for someone in a much quieter location that may be desirable. I do have a precision noise head, and measured the noise figure at 7.6dB, using the Y-factor method. That is pretty good, compared to many other rigs, and is certainly good enough for my location. All measurements are with the internal preamp ON. The receiver is essentially bomb-proof. I have a number of well equipped stations very close to me that used to completely flatten my 706, but with the 3000 I don't even know they are on, except for the huge peaks on the panadaptor! I have worked a few stations on 6 running the F5000, but so far noone using a F3000. I know they are out there; load up a piece of wire and get on. For the next couple of months the band is going to be hopping! 73 Alf NU8I Scottsdale AZ DM43an _______________________________________________ FlexRadio Systems Mailing List [email protected] 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/
