The other day when I was doing an RF survey for my little iDEN EBTS tracking project, I noticed that a couple of transmitters are not exactly on the designated Hex frequencies. For example, if you look in your iDEN handset diagnostic mode, you should see a Hex code like 2AC which is 684 in decimal or 859.5500 MHz for the PCCH forward frequency. When I look in the spectrum analyzer, I noticed that the "M16-QAM" modulated signal is about +200KHz off the suppressed carrier frequency! I am just wondering if someone out there encountered this before. I think either the PA is going out of whack and/or the switch operators/technical personnel must have programmed it wrong. Anyone ideas?

well being that Sprint is treating Nextel like a red-headed stepchild, not surprising. They turned over the maintenance and management of both it's iDEN and CDMA network to Ericsson, so yeah, what a surprise- their BTS may be off and the swedes haven't got around to fixing it.

I've had tickets open with L2 support at Sprint since June on two iDEN sites near me that aren't working well. It's still not fixed. And they wonder why 6 million users dumped iDEN?
