Ah. I see we've both presented our operating preferences as if they reflect those of the majority of contesters. Sorry for that. There have been posts from both sides of the fence. Some ops apparently can memorize or hear the radio's settings, and other cannot or don't want to. Thanks to N1EU

Not a bit. Rev B will get you there perfectly. Rev C streamlines the process to remove perhaps 5 minutes of work, that's all. Because many steps were moved around, if you've started assembly with Rev B I recommend you finish using that Rev to be sure you don't miss any steps. Ron AC7AC

Well, speaking as someone with an almost big-gun station, and one who has operated from several of the biggest stations in the Northeast, with some of the best operators on the planet, and also one who has had the rate meter up to 350/hr in Barbados, I can tell you that knobs can and do get

I would guess not very many, judging from the serial numbers being reported here occasionally as they are received in the field. 117 the other day is the highest SN I can remember. Jerry W4UK At 11:32 PM 12/1/2007, [EMAIL PROTECTED] wrote: ... I wonder how many K3's can be shipped per week?

I think you meant that they don't have group delay variations. That's right, even FIR filters have group delay. It's typically equal to half the length (impulse response) of the filter. Actually I have a feeling that constant group delay is only true of finite impulse response filters.

2007-12-01 Thread n1al
The amount of ringing of a bandpass filter depends on the bandwidth of the individual poles (crystals or tuned circuits) that make up the filter. One way to make a bandpass filter is to cascade a bunch of 1-pole (single-crystal) filters with isolation amps so they don't interact. You select the

Serial numbers of units shipped and reported by their owners on the reflector are shown here: http://www.zerobeat.net/mediawiki/index.php/Main_Page Only under the most favorable scenario would second production run units ship before year end 2007. You won't know how many units can be or are

Good Evening, Winter is truly here; the snow is getting deeper as I write. Because I may be snowed in for a few days I drove into town with the 4WD F-250. Good thing I took that instead of the Ranger because on the way back it got very slippery. Up here there were six inches of snow when
