RE: [Repeater-Builder] Looking for info on DB products cans (6meter)
Randy, Ok I have cleared my head. This is the 6 can helical duplexer. To get it to 6 meter you will have to cut the harness. I will look to see if I can find my notes on this duplexer mod. It is a good unit and I have used them on 500kc split machines with excellent results. > -Original Message- > From: Randy Long [mailto:[EMAIL PROTECTED] > Sent: Thursday, May 20, 2004 10:22 PM > To: [EMAIL PROTECTED] > Subject: [Repeater-Builder] Looking for info on DB products cans > (6meter) > > Hi, > > I have a set of DB products cans, model #DB4032.

RE: [Repeater-Builder] Looking for info on DB products cans (6meter)
start screwing the knob till it tunes on the spectrum analyzer to your freq. they will go that far. Also I do have modes some where to make those pass/notch Now just in case my mind is slow, the 4032 is the big tall can right? Oh heck now I will have to go look :) Kevin > -Original Message- > From: Randy Long [mailto:[EMAIL PROTECTED] > Sent: Thursday, May 20, 2004 10:22 PM > To: [EMAIL PROTECTED] > Subject: [Repeater-Builder] Looking for info on DB products cans > (6meter) > > Hi, > > I have a set of DB products cans, model #DB4032.

Re: [Repeater-Builder] Looking for info on DB products cans (6meter)
From the specs page at www.repeater-builder.com % DB4032-8A (30.5-50 MHz) % % Type: 8 helical resonators, bandreject % % Minimum freq. spacing 0.5 MHz % Insertion loss 2.0 dB % Max. continuous power 150 watts % Tx noise supp. at Rx freq. 80 dB % Rx isolation at Tx freq. 80 dB % Temperature range -10 to +50C % VSWR 1.5:1 They will go to 6m just fine, but if you have only 4 cans you will have desense at a single site repeater, especially if you are running a solid state TX. Best keep your hollow state TX going. And you may want to add some notch stubs. Mike WA6ILQ At 08:21 PM 5/20/04 -0600, you wrote: Hi, I have a set of DB products cans, model #DB4032.

They will go without anything, I have the 38mhz 4set and they worked good on a tube transmitter but you will probably need 6 to go with transistor pa deck. Adding notch stubs will help but if you have only 4 you will have a lot of desense with silicon finals, try to keep your bottle finals going.
