PACE MSS100 Analogue Satellite Receiver




New Notes: As of 12-07-2000, all Pace receivers are spoken for, however I will try and see if I can get some more.....

Have had it confirmed that all receivers are gone - the remainer (some 50,000 odd units! ) was sold to an Australian firm for an unknown purpose. (Probably for the purpose for which they were manufactured - receiving analogue satellites...)

There are about 3 Uniden SQ500e receivers still available - these also have 250 channels, fixed bandwidth (27 Mhz, I think), and whilst the sound intercarrier frequency is adjustable, the differance between the left and Right audio channels is fixed at 180 kHz. They do, however, have an 'IF' frequency display on the front, and (I think so anyway), a slightly better picture output - bandwidth seems flatter.

The Auckland ATV group has some Pace MSS100 Satellite receivers for sale, suitable for use as FM ATV receivers, with the aid of a preamp or LNB depending on the band in use.
For 23cm use, a low noise GAsFET preamplifier should be used. Due to bandwidth limitations in the 23 cm Ham band, 1/2 satellite bandwidth (approx 15 MHz) is normally used, which requires the use of a x2 video amplifier to boost the composite video signal from 0.5 volt pk-pk back to 1 volt pk-pk.

The receiver has 250 channel presets, which many parameters about each channel can be stored, such as -:

Channel Name, 10 Alphnumeric Chracters long,
Channel Frequency in GHz, Polarisation, 22kHz Tone, Selectable 1 of 2 IF inputs, LNB Power
Video IF Bandwidth 15 / 27 MHz, De-Emphasis PAL or Flat response
Audio type, Mono or Stereo, Independantly settable audio subcarriers in 10kHz steps from 5.00 MHz to 9.00 MHz
Selectable Audio bandwidth and de-Emphasis
Multifunction remote, including system settings
Selectable UHF channel modulator, channel adjustable via remote
Clock and timer selections.

The receivers are complete with power lead, remote control (no batteries thou) and instruction manual.
The asking price was $NZ25, 1/2 of which was donated to the ATV 'Jam Jar' fund, under the care of Mike ZL1ABS.
Any additional donations to the ATV 'Jam Jar' fund would be gratefully accepted, as there are always projects in the pipeline for which components and other materials need to be purchased.
There were a limited number of these units available, as the source disposed of the remainder at the end of July 2000 - sold to an Australian firm, I believe.
