Re: Topband: Meaning of AGC Delay
Bob, Not sure if Yaesu means the same thing, but the old meaning of Delayed AGC is that it kicks in at a higher threshold, which generally makes weak signals easier to hear. It also reduces the AGC's reaction to noise. You get some of the benefits of AGC Off while retaining some protection to your ears. Gary K9AY __ Subject: Topband: Meaning of AGC Delay Dear All, I am looking at the AGC parameters on the FTdx9000D. Yaesu uses the term delay but does not define the term. Other manufactures use the term attack time which I understand to mean how quickly the AGC reacts to a signal at the threshold level. Hold time means the period of time the AGC voltage remains constant at the peak level once the AGC is activated by a signal above the threshold. Decay is the rate at which the AGC voltage is reduced (gain increased) once the hold time expires. So, two questions: 1. Does anyone know for sure what Yaesu means by the term delay? Does it have the same meaning as the decay time? Different authors uses different terms to mean the same thing but do not define the terms - leading to confusion. 2. When we adjust the AGC delay on a Yaesu rig, what are we doing? Thanks for any clarification. 73, Bob AA6VB ___ UR RST IS ... ... ..9 QSB QSB - hw? BK

Re: Topband: RI1ANF
Antarctic Continent is a bit difficult these days. I have a few contacts in the 80s - 90's, but pretty skimpy from year 2K. I did work VP8CTR in Feb 1998 but didn't note the QTH. I never sent for the card. Any ideas on the QTH? 73 George W8UVZ I'm pretty sure DP1POL was active on TB in 2010. I worked him on 80, 40 and 30m and seem to remember he had 100w on TB?

Re: Topband: RI1ANF
My card says Ukrainian Antarctic Station, operator Roman, UX1KA. He was on Galindez Island. It is strange to me that they got a VP8 call. 73 N7RT - Original Message - From: George w8...@voyager.net To: Jeff w...@arrl.net; Topband@contesting.com Sent: Wednesday, June 06, 2012 7:36 PM Subject: Re: Topband: RI1ANF Antarctic Continent is a bit difficult these days.

Re: Topband: RI1ANF
George, VP8CTR was very available in 1997/98. QTH was Vernadsky Base on Galindez Island, AN-006. The operator was the much-traveled Roman Bratchik, UX1KA, EM1KA, EM1U, UA1OT, 4K2OT, XY0RR, 3W/4K2OT.

Topband: 7O6T LOTW
My 7O6T 160 mx QSO was just confirmed by LOTW! That's fast! I can start breathing again now. His sigs were so strong when I worked him that I was afraid that it might have been a slim. My contact was grayline on his end at 0148 on the 13th. Jeff, was that you or Yuri? -- Ken - K4XL BoatAnchor Manual Archive BAMA - http://bama.edebris.com ___ UR RST IS ... ... ..9 QSB QSB - hw? BK
