Doug, The 19D424984G1 is an IMTS Station Voltage Control Panel. It is designed to run on either -48 VDC or -24 VDC, and is intended for controlling the output power of 50 or 100 watt GE Mastr II IMTS (Improved Mobile Telephone System) base station transmitters. One of its functions is to cut back on the output power during intervals when only the idle tone is transmitted. The specific band in which the panel operates is determined by the part number of the RF Detector Module: 19D424785G1 is low band 19D424785G2 is high band 19D424785G3 is UHF
The manual that covers this unit is LBI-8878, but alas, this LBI is so rare that it was not scanned for the GE LBI database. Needless to say, IMTS went away many years ago as cellular technologies took hold. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Doug Sent: Sunday, June 07, 2009 7:04 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] 19D424984 G1 Tx Monitor panel Has anyone any information on this panel. I searched the LBI's but nothing. Google also wasn't much help. It is a GE panel from all the numbers it has on it and since the directional coupler uses UHF connectors, I would suggest that it is for VHF. Any help would be appreciated. Doug VE5DA
