If Matt Bush is still involved with the Micro Comouter concepts that would be a could way to go. Matt sets up the radio and the hooks up the controller to it. I have two of them one is a uhf and one

Yes, I have purchased a UHF Mastr-Exec II from MCC. It currently runs my 444.55 mhz repeater here in the Tacoma, WA, area. My experience with their work is that they are outstanding. The conversion

The document I have states the operating freq's are 52.87/53.87 Should be close enough to work anywhere in the 52/53 range. I'm running 200 watts into the thing (50 w over the cont. power rating)

Hi Chris: You would think so, but why is the SWR so high going into a dummy load? What I'll try is use your frequencies and see what I get for loss and isolation. That way we'll know if it's

Hello again Tom.. I have some limited experiance tunning duplexers on two meters ( Wacom ).... It may help to draw yourself a picture of what you want your duplexer to do. For example on mine for

Hi again guys: Here is a partial view of the 4032 duplexer. maybe someone can explain to me how these things work, then I could scale it up to 53 Mhz???? (Please use a non-proportional font)

Hi Ed: It was tuned for 45 Mhz TX and 46 Mhz RX. I thought I would have to modify the cables, but without a formula for calculating the lengths, could become a real hassle. On this unit, they have

I saw a picture of similar unit, is this duplexer factory tuned for 6m? If not, you may need to trim or adjust all the cable lengths and stub lengths. I rebuilt a sinclair hybrid ring duplexer, 2m,

Hi Guys: Can anyone point me in the right direction.....I started tuning up my db-4032 6 meter duplexor and after setting the cans, the SWR on the TX port is over 3-to-1. When I got the set, it was

That's what I'm using now. Took the spk/hi terminal, through a 2.2uF cap into a 10k pot, feeding the mic/hi terminal. I find the TX audio "rough"? I thought it would be a smoother response, but I
