The problem might be he lives in Missoula and it is surrounded by high mountains wich would mean Salt Lake center might not be possable.
Like I said, according to the Airport/Facility Directory the Salt Lake Center RCAG (remote transmitter) on 119.750
is located in
Missoula, if this is actually correct then reception of the
controller should be possible. The Salt Lake Center low sector (ZLC 19) covers the same area (up to FL290) and you can hear the controller on that frequency 133.400 loud and clear.
Aircraft reception will be blocked by the mountains to some extent but you should be able to hear the aircraft in the vicinity of Missoula in the western half of the sector, like you can on the low frequency 133.400. The adjacent high altitude sector to the south (ZLC 06) on 132.400 is in the scanner and you can hear aircraft in the western part of that sector (the eastern half is blocked out by the mountains). It just seems to me that if you are going to put the adjacent sector to the south in there, why not also put in the sector that is directly overhead, especially if you can hear the controller ? Unless there is interference issues with that frequency, etc. ?
Normally I'm not a fan of loading up the radios with more frequencies (like some radios here that have way too many and are very difficult to listen to), but in this Missoula case the traffic is very light and the addition of the high altitude airspace, that covers the
same area as the low sector that is being scanned, should work nicely. Again, just a suggestion. DJ
