Thanks Skipp. Yes, you're right. I'm in the process of locating the "guy" to talk to. I had a big awakening this morning when I went to the base and tried to find the equivalent of my old job, Avionics Superentendent, and it has drastically changed since I retired in 80. However, through the Command Chief Master Sergeant, I'm on the track and, yes, I'll be nice. I started in Armament & Electronics (A&E) which begat Avionics Maintenance Squadron (AMS) which begat Component Repair Squadron (CRS) which has evolved into Component Maintenance Squadron (CMS). It's apparent that the military thrives on change...either that or they keep moving things so nobody can figure out what they're doing.
Popcorn is what we call it, and we can see what appears to be spread spectrum pulses on the scope. A couple years ago, it would be on during the day and off at night and weekends. Now it's 24/7 and getting stronger. And, I miss-spoke, it's 420 - 450 as you said. At least you give me a little hope with your comments and if I can find that friendly someone and buy him (her) a beer, I might do some good. de WD7F John in Tucson ----- Original Message ----- From: "skipp025" <[EMAIL PROTECTED]> To: <Repeater-Builder@yahoogroups.com> Sent: Wednesday, August 20, 2008 9:08 AM Subject: [Repeater-Builder] Re: SADL or EPLRS ? > Re: SADL or EPLRS > > Hi John, > > You MIGHT be able to find the contact person for the system. > Probably your first task... followed by trying to open a very, > very friendly dialog with said person(s). > > Advise them they are able to operate their EPLRS System below > 420 MHz where the interference would be less to BOTH parties. > > A sidebar question of user authority in the band is based on > emission designators.
