The NanoVNA-V2 seems to handle doing the pass part pretty well. You're measuring return loss there, and it seems to handle that just fine. Only question I might se is if the frequency standard is

? It is an older variant of RG-393. I know it's 393 and I know it's 50 ohms. Apparently, I didn’t receive the original post, only your follow-up response. Questions: 1. What is the measured

Roger, In hopes of answering your original question, I got my hands on a DB212-2 originally on 37.7MHz and shortened the antennas and matching section for 6 meters. The 35 ohm matching section

I don't think you understood my question...I am asking about this specific cable. It is an older variant of RG-393. I know it's 393 and I know it's 50 ohms. I'm aware of every RF connector. I'm

Hello all, would anyone have any tuning information on the Varden duplexer 146-148mhz. I know its a long shot, but no searches on the web produced any results. These were made by Varden

Internet has all your info, its 50 ohm and would be great for jumpers between a repeater and other stuff. Connectors are available in many types.

AH6LE, Ken, I wonder if? some of the same UPS AT 220 MHz amps may show up at the next Rickreall hamfest, I missed the one at Rickreall this Feb.? but maybe the one in the fall could have some

Mine didn't have any fans and no? cases on any of these amps either but they were complete and the box was marked as working 220 MHZ ACSSB amplifiers. The amps all included the T/R switch, a low

Hi all, I recently just picked up an item from Facebook marketplace, taking the chance on it. It was a roll of unknown coax. The seller took pictures of the roll and the end of the cable. I counted

Hi Scott!? ?All the 901 stuff has been sold.? ?Thanks for asking. Craig AA6CG

I'm not reassigning the RS232 pins 2&3. Channel select uses AUXIO1 to AUXIO4, pins 20 to 23. Joe

Best of luck. tnx Mike / K5JR Alpharetta GA

Thanks for your input, however I'm looking for help programming the MTR2000 instead of a functional description. 73 -de John NI0K

The repeater certainly would pass encrypted traffic without needing to decrypt it, but I'm wondering how traffic originating from the repeater would be encrypted, say a phone patch or some sort of

Encryption only applies to terminals (portables, mobiles etc). Basic encryption is usually good enough to avoid other radios or scanners from listening in. Advanced encryption is usually for somewhat

Hi Tim as other's have said program through the Mic socket, the HD15 on the back is for a Data terminal well the UK one was .. looked after a fleet of 50 till we swapped them out for Icom :) I think

Wouldn't the repeater just pass the encrypted audio from mobiles and handhelds? I'm trying to logically think whether the repeater needs to unencrypt it to repeat it or not. In the analog world, my

Not really. The RS232 pins can't be reassigned. Ken

Very good point. I use pins on the db-25 of one of my TRK repeaters for channel steering. With the db-25 off and no steering pins grounded the repeater will fault and not key up. Joe, K1ike
