screen shots of the "new" duplexer tune are in my gallery. these were taken off of the network analyzer it was tuned with, it shows insertion loss and swr.

I hope to put it into service soon and add the power amp I have standing by.

@JohnE, How are you guys up there? I miss NY/NJ a lot..LOL. I was a member for www.metrofireradio.com for over 10 years or so, and also with JCES out of Lyndhurst,NJ. They are both running strong. I miss those guys out there. Be safe...

might move this to SI if I can get the space. I have to see how long/type of cable/antenna is used the plot the pattern and see if its worth it.

pre-selector put back in line, still having desense issues will look into that when I have time to sit there for a few hrs. may have to get some pass/notch cans.

removed my homemade RICK cable in favor of a real RICK the machine now has 1.5s of hang time. if my users have not been sure if your going through it you will be now.

one small problem I noticed after I left the site is when the morse ID goes out you get cut off, so bear w/it for now till I find out why its doing that. goes out every 1/2 hr so listen for it.

575 is now at full power. if you haven't heard it before you should now. will be testing all week.

I have not addressed the morse problem yet. I took a couple of hrs to rearrange the rack it is in to accomadate the new supply and amp. I have decided to to put a backup on this as it will only cost me for the batteries and some time to do the work.

was up at the site last week checking a few things. I have a slight SWR issue nothing my isolator can't handle but it will need to be addressed when it gets warmer and no snow on the deck.
