Ken, I just got a note about this from Vic, K2VCO, which I hope he posts to the reflector. This is, apparently, a known bug in the firmware which will be fixed in the future. For the time being, the workaround is to set IIR to ON in the FL:x menu. After Vic mentioned that, I sort of remember it crossing the reflector, but had dropped to the bottom of my priority bucket. ;-)
Thanks for the note and I'll do the workaround until the firmware fix arrives. I really don't use anything less than 150 Hz very often, but it will be nice to have it available when I'm playing around. 73, Bob K5WA -----Original Message----- From: Ken K3IU [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 27, 2008 11:51 AM To: Bob Evans Cc: Elecraft Reflector Subject: Re: [Elecraft] K3s in WPX M/S - WOW! Hi Bob: Thanks for the report! Re: your comment regarding the 50 and 100HZ bandwidth. I am surprised to hear what you report. I have the 200Hz filter in FL5. I just put the Elecraft XG-1 on ANT1 and tuned to the 7040 freq. With the bandwidth set to NORM (400 Hz) I show a S9 signal and an audio level (dbV Alternate display) of 31.7. When I narrow the bandwidth to 50 Hz, signal strength stays the same at S9 and the audio level stays the same. I do have 8 dB of gain set into FL5 where the 200 Hz filter lives. Without that additional gain, the S meter drops to S7 and the audio level drops to 30.5 dB when that filter switches in. I found it very usable at the 50 - 100 Hz bandwidths. 73, Ken K3IU K3 #202 ~~~~~~~~~~~~~~~~~~~~~~~~~ Bob Evans wrote: > I finally had a chance to put both of my K3s on really good antennas > (2 el 40@ 140', 5 el 20 @ 130', 5 el 15 @ 120, 5 el 10 @ 110', 3 el 80 > (delta > loops) @ 110', 140' shunt fed on 160M, 600' beverage pointed NE).
