[Repeater-Builder] UHF Repeater

Hi all, I have a UHF MSR2000 repeater and various RX TX modules. The exciter module is a VTE4001A for 403-430 MHz. The RX module is a VRE4001B for the 450-512 MHz. Has anybody had any success tuning these to the 430-450 MHz Ham band? The curious part is that the existing RX (VRE4001B) was u

Hi Ron, Thanks for the info. That's exactly what I'm afraid might happen. But, as you say, the MSR2000 has better shielding and it's worth a try. Since it is unlikely that both receivers will be receiving their signals at the same time, I can always give each receiver, and it's mating far-end l

While investigating a problem with a Low-Band (46 MHz) repeater, we determined that the antenna harness on a DB 212-4 was bad. It turned out that two UHF female "T" connectors were bad. The center pin of the "T" was, instead of screwing into the center of the through pin, making contact with the

Not just the second harmonic. A power supply with a 120 Hz ripple on it (poorly filtered full wave rectification) could deviate the TX sufficiently to cause "some" PL decoders to see it as a 118.8 Hz PL tone. Tony, VE3DWI -Original Message- From: Steve Grantham [mailto:[EMAIL PROTECTED
