It is not so much about the radials as it is how much coupling it is to the coax.? Look at the folded dipole antennas.? They do not have radials but make some of the best repeater antennas.??

They will easily tune down to 440 and even below some. As was pointed out, they are designed as a 3 notch filter high and 1 low (referring to the frequency you want to pass). They have about 80 db of

Look at the chip inside and see what version firmware your CAT1000 is running. Then look for the correct version manual. Also, check what hardware version you have. Look at the telephone jack on the

Well, certainly an antenna that presents a poor impedance match will not work well in a full duplex system. Ringo's are essentially and end-fed half-wave-sorta-kinda. They may or may not present a

RF Guy, That helps. I want to use it with an Allstar duplex node. I don't know if it will tune down to the UHF ham band yet. Thanks Tony, W2KJV

Do I recall a thread long ago that an antenna without radials misbehaves in duplex mode? Something like a Ringo Ranger. I looked for that thread but couldn’t find it. Tankew. Richard WB5NEN

It is a mobile phone duplexer so the high side (mobile TX) say 459 MHz, has three notch filters that reject the TX noise falling on the low side (mobile RX) 454 MHz. The low side (mobile RX ) 454 MHz

Thanks Jim. Here are a few pictures. Tony, W2KJV [email protected]> wrote:

That being the case, a simple spare switchboard should be enough.

I have a Cat 1000, I can give you a copy of my software.

Around here they DO swoop in if anyone doesn't have a resale license and does it more than so many days a year. They have to because a group will swarm in and kick everyone out and make an offer to

Have you ever thought about looking at the repeaterbuilder site for the manual? It's there. Can't really help you with the rack cabinet. Just get a blank cabinet and start in. There never was a front

There are a few aftermarket tone remote adapters that actually work for multi channel for some radios. It is a pain to set levels sometimes and you often have to retune the notch filter for low level

A picture of it would help immensely. 73, Jim W7RY -- Thanks and 73, Jim W7RY

Yes they will. Any CTCSS encoder/decoder should work as long as (one way or another), it provides full duplex operation Ken

Hello Ken, If it comes down to it will the boards work with your cable setup and board you supply? ?? I understand it takes special software and it can be costly to get the software but as time goes

Another issue with the Midian boards is they're not field programmable as it takes a special programmer to do so. (we looked at Midian but obviously decided they're not what is needed) Ken

Interestingly, the schematic shows RA/RD with a spec of 80mv and 400mv respectively. It also shows an TA and TD pins. Those are Kenwood's nomenclature for RA = De-emphasized audio RD = Raw

Hello Jamie, Has your club found a buyer for the controller??? I would be interested in talking with you about it. Thanks! Steven H N8RLW
