I have used my QDX with a WA2EBY amp with a COR (carrier-operated relay) function.? So far, there has not been an issue.? Before the amp keys up, the antenna is connected to the output of the QDX.?

Thanks ... Hans. And Sverre. Looks like a perfect fit. Wes -- wes377@...

Speaking of sequencing (which makes a lot of sense), with the PTT hooked up, is there a setting in configuration to delay transmission for x time ? (The other Joshua) HI - sure send me an Alex link !

Found exactly what I needed on Amazon - a 10 foot length of Amphenol RG174 and a female-female connector. Tnx all for the suggestions. -- Jim / K7TXA Eagle, ID SKCC 10447 BUG 301

Mr. Ellis, the reason I ask is the same reason Donald made his comment.? The QDX is a bit sensitive to poor impedance matches on its output so when you transmit and the amp is figuring out what to do

Donald, That makes great sense. Do you have any specific examples of what has actually happened to a radio in this configuration? I will have to play with the PTT port and see how it does. Joshua

Joshua KJ7LVZ Yes, RF sense for TX and band selection. As Donald points out, maybe an issue? The amp does have a PTT port and even a menu for selection between either "ICOM" or "XEIGU" but not sure

James, Yes, it's a voltage and amp controlled board, found on Aliexpress a while back. Shoot me a note if you need a link. KO4AWH@... The Case is indeed printed. I designed it for a quick means

Ron, I don't know if any links exist to the original Clockbuilder Desktop, but I have the installation .zip file and can send you a copy if you need one. I've used it and the new Clockbuilder Pro. The

If you go to the Superbat WWW site you can order a premade coax feeder of the length you require. https://www.rfsupplier.com/ -- Compton VK2HRX Sydney, Australia

Hi Willie, No, never bothered to write this up as its final design is still not done. Are they ever? Case lettering, serial/USB ports, and PPS ports are on the list. Also, the CAD used for the case

Here's one Jim. It's 15' so a little longer than you were looking for but not too bad...

Heck I was and other were running BPQ back in the 90's. A great AX25 packet switch along with the famous F6FBB BBS software. -- - 73 de Andy -

I appreciate all the help.? I have enough information to figure it out. Thanks to all!

The supplied coax is usually RG174. But any 50 Ohm stuff as an extension will do. -- - 73 de Andy -

I’d like to place my QLG2 antenna just outside my shack; already have a conduit in place for several antenna coax runs. Unfortunately, the supplied coax for the GPS is about three meters too short.

Bob, It looks as though to generate signals in the 144mhz range, the Si5351 will be using a fixed output divider of 6.? A simple Si5351 library that uses fixed point and does nothing fancy but does

I have built many QCX minis. I have never noticed this before, but then, I never looked before either. However, once I noticed the one at 7,052 after I had replaced the SI5351A, I started wondering.
