The last known address and phone for Spectrum was:
Spectrum Communications Corp.
1055 W. Germantown Pike
Norristown PA. 19403-3924
They seem to be out of business.
Google suggests that the address seems to be a rent-a-mailbox place.
Is there anyone in the Norristown area that could drive by and see what's really there and ask a few questions?
This web page may be the only collection of Spectrum information on the web.

This is a 10w continuous duty unit. The manual is dated 12/1991.
|Spectrum SCT-1500 service manual 1.6 MB PDF courtesy of W9FS
This manual has a spec sheet internally for the 136-174 MHz, 406-512 MHZ, and 806-960 MHz digital / analog paging transmitter, but seems to be for the 900 Mhz unit only. It also mentions the SCP30 power supply and the SCA1000 power amplifier. Supposedly the SCT-1500 is a 100w continuous duty unit. The manual itself is undated, but some of the prints have 1993 dates on them.
