Hi All,
I’ve answered my own question !! just tweaked C21 and C23 and now have more ‘oomph’ on 20m RX, with same power output !!. Even though I’d tweaked these for max power output originally ?? Anyway, sorry for the bandwidth. Regards David _____ From: David Douglass [mailto:[EMAIL PROTECTED] Sent: Sunday, 11 March 2007 8:32 PM To: '[email protected]' Subject: K2 - 20m receive Hi All, I’ve have a suspect issue with low RX on 20m. The level of background noise on 20m is substantially lower than other bands, and in general the RX level on 20 seems down to other bands. I’ve suspected this of being the case for a while but just noticed more over this weekend in the BERU contest. I can still receive stations, and local VK and ZL still give strong signals (s9 plus), but I have a feeling something is amiss. The receive level on 20 is comparable with other bands with the pre-amp turned off (and before you ask, I have the pre-amp on). I have full power out (on K2 and K2/100) on 20 and therefore think that I have the alignment pretty much OK. Is there any parts in the 20m RX path that I should suspect that are specific to receive on this band, and not shared with TX or neighboring bands? I plan to do a full RX and TX alignment, once I have a good nights sleep, but thought I would check here first !! Thanks David, VK2NU -- No virus found in this outgoing message.
