As a reference for this ZDV High Altitude feed I put together a chart (pdf attached below) that shows the applicable sectors and frequencies in range of Denver. The redish circle at 200 miles represents the approximate reception range. Frequencies have been confirmed from monitoring. Any updates or corrections always appreciated.

Suggestion

you are missing 2 very close sectors that involve DEN A/D in not keeping 132.175 and 127.025 on the highh feed and 125.675 is a sector that is quite out of range(barely hear loud traffic on that one and 127.95 if i am not mistaken is a non working frequency.

can you please add 132.175 and 127.025 while deleting 125.675 and 127.95

also thinks that alb center 133.05 and kc 133.45 should be trimmed off

I keep forgetting you post/PM your messages. I responded via PM. Let me look over the .pdf JetScan just posted and I'll get back to you...

Turned on 10dB of attenuation for ZDV low just now - a bit to much amplification for it to handle w/o it.

Side update, house was hit by lightning last week, still dealing with various problems. It's back burnered almost everything "hobby" related.

I think [insert Deity here] is trying to tell me something. Hahaha. Wow. What a week.

The LiveATC gear survived the strike, and with some up and down for killing the power to the whole house for inspections and repairs, KAPA TWR is still generally plugging away.

Saw some of your tweets and pix - ugly  shocked
Just keep that great APA feed running brother!
I picked up a mint Pro-2006 to split ZDV High into North and South (11 freqs each); should be online within the next week or so...

Sorry my promised "assistance" has turned into a total fizzle, man.

Tonight I had a first... Troubleshooting the malfunctioning continuously keyed IRLP setup, I ultimately found the GE CTCSS receive decode board blown in the MASTR II. Even more interesting, it blew in such a way to continuously key the transmitter?

I didn't bother figuring out why, since everything of interest in a GE CTCSS decode board is inside their proprietary two ICs standing above the board. I just swapped it for a spare one out of another receiver.

Here I thought it would be the IRLP board itself.  Heh. Next I thought it might be the keying circuit on the 10V regulator card. Nope. Last thing I tried was pulling the decode board.

Lightning does whatever it wants to do, as always.

Yay for swappable radio components. No single board radio, the MASTR II. Stuff can actually be worked on. Yippee.

And now the coax is making crispy crunchy noises on receive if its wiggled, too. Going to have to order up some new LMR-400. I have a suspicion the link yagi was hit or partially hit during the storm. One of the branch circuits that had a blown ground was the one feeding the MASTR II. I think the UPS saved the PC and somehow it managed to survive also.
