It's just a matter of retuning. You should be able to do it WITHOUT replacing the loops. First tune the individual cans (seperated) to the desired pass frequencies, then carefully tune the cap to move

Chuck, How do you figure? That was damn near 30 years ago, if not. It's the lack of participation that's causing these sorts of problems. I think you can read between the lines

All the more reason for folks to focus on making use of the 220 band. Develop stuff for DMR for 220, and you'll have it chock full of repeaters spitting out crap from the other side of the world for

I don’t have a dog in this hunt, but I would be careful what I posted in a public forum. Even if true, it is obvious you posted this in a malicious manner, opening yourself up to a libel charge, or

Many duplexers don't use a different loop assembly for each "side" of the duplexer.? The DB406X series is NOT one of those, but you can still tune the notch to either side.? Simple series L/C BpBr

The short answer is yes, it is a function of the loop geometry. The longer answer is that there is no single "high pass" or "low pass" loop for all bandsplits; what may be a high-pass loop in one

Back when the UPS 220 MHz fiasco came along, I told myself NOT to invest in anything on that band. I realize that this is a "cop out," but I could foresee lots of head-banging in the future. I think I

I help out one or two days a week at a local 2-way shop.? Between the shop, myself and a couple of friends we've purchased around 40 of the BlueMax cables, Id say that 80% have been FTDI, the rest

I know I've written about this before but since then the threat has increased to the 222-225MHz Spectrum. The FCC has issued additional licenses to the Company "Chaos" with high powered Radar Testing

Hi guys, Does anybody remember these? I sent it off to Tasmania (2014) before I had had any real experience of duplexers. I had just acquired a? cheap Atten 0-1500 MHz spectrum analyser & tracking

Blue Max cables work well and yes the FTDI are the best Les Keegan?N4LPK?

I could do that. Frank

You're aware there is an NXR-1000-R series now for those of us who need half-duplex base stations, right? They have PIN antenna switching enabled inside, and the RX jack isn't connected to

This is the wrong Don, but I just measured a couple of mine. This is tip to tip of the male pin. Very close to the end of connector also.? 3.74" Or 3.737" to 3.745", and I doubt you can cut a coax

I asked this question before, but the string got a little bit sidetracked.? If I want to convert a DB4060 Series can that is currently set up for Pass Low / Block High to Pass High / Block Low, what

There used to be a program called Echo Producer that had some very useful features on it. http://homepage.eircom.net/~ei4jr/EchoProducer/EchoProducer.htm [email protected]> wrote:

Thanks to all that responded to my question. An order has been placed with BLUEMAX49ers and prog cable for Icom IC-121S is on the way! Tim AE7TH Vashon Is., Wa.

I do. I will back home Friday and I can give many more details.

Hi again Frank, the other one that is coming available has a shorter cord since it is mounted in my repeater cabinet. Sent: Thursday, April 17, 2025 4:11 PM To:
