JohnE Posted May 7, 2013 Author Report Posted May 7, 2013 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. Quote
unit997 Posted May 25, 2013 Report Posted May 25, 2013 @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...

JohnE Posted May 25, 2013 Author Report Posted May 25, 2013 all is well. both machines working wellhope all is good by you. Quote
JohnE Posted June 12, 2013 Author Report Posted June 12, 2013 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. Quote
JohnE Posted August 7, 2013 Author Report Posted August 7, 2013 pass/notch duplexer installed today and removed pre-selector, will see how that works for a few weeks. have PA but no supply to run it. Quote
JohnE Posted August 28, 2013 Author Report Posted August 28, 2013 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.

JohnE Posted October 22, 2013 Author Report Posted October 22, 2013 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. Logan5 1 Quote

JohnE Posted January 24, 2014 Author Report Posted January 24, 2014 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. Logan5 1 Quote
JohnE Posted February 22, 2014 Author Report Posted February 22, 2014 575 is off line indefinitely. Quote
PastorGary Posted February 22, 2014 Report Posted February 22, 2014 John - What happened this time? ... Tech glitch, or unauthorized traffic??? Quote
