Masters Communication RA 42 Cable is also on his site as where to get it. I have done 3 of these. Dean K9QB

Re: VHF MTR2000 Poor Receive Performance
Would a signal generator set to the notch frequency (maybe set to +10dBm output) and a sensitive receiver tuned to the notch frequency provide a "final fine tuning" capability for the entire cavity

Re: VHF MTR2000 Poor Receive Performance
Yes, if those are the factory supplied cables (and Tees) and the desired frequency is within the factory specified range then something else is likely the issue. But if, as is common on this group,

Re: VHF MTR2000 Poor Receive Performance
Good point, Eric. When I was messing around with cavities I found best results when I cranked the VNA's source power up all the way. I don't remember but I think it went to something like +10 or +15

Re: VHF MTR2000 Poor Receive Performance
Sounds to me like you don't know what you are talking about with this duplexer. Leave the cables alone. This duplexer is designed for the cables to be used for the full frequency range specified for

Re: VHF MTR2000 Poor Receive Performance
Is a notch depth greater than 90bB exceeding the capabilities of the test equipment? Eric

Re: VHF MTR2000 Poor Receive Performance
Sounds to me like your inter-cavity cables aren't close enough to the right length. You probably already know this but I'll state it for those who might not: The reason the cable length is pretty

Re: VHF MTR2000 Poor Receive Performance
I went ahead and tried to work on the receive/high pass side. All 3 cavities were already at their best return loss from when I was working on it the other day. So I went ahead and tuned the notches

Connecting Yaesu DR2X Repeater to Raspberry Pi/Allstar?
Someone asked me yesterday how to connect an Allstar node to a yaesu DR2X repeater, and mentioned they would like something plug-and-play. Is this product <https://www.customcomms.net/products> the

Re: UHF Cans?
They are Telewave VHF pass cans. Most likely from a Telewave VHF transmit combiner. Most older wide space transmit combiners used simple pass cavities. 73, Jim W7RY -- Thanks and 73, Jim W7RY

Re: UHF Cans?
They look like the ones used on 900 Mhz paging transmitters. Probably tuned around 928 - 932 Mhz. Will handle a lot of power.

UHF Cans?
Can someone identify these cans? They are 24" tall and 10" in diameter. Both loops have "insertion loss" adjustments but no marking other than that. I haven't sweep one yet. Bench is a little full.

The RIM Maxtrac and the RIM Alinco are the soundcards that connect your radio to your computer. I do not know for sure but you may be able to use them with Winlink. They are designed to be used with
