MX800

Information on the MX800 Base Station from Spectra Engineering

General Info

I've found the power out to drop off to less than 50 W (40W normal) at 225 MHz. The MX800 doesn't appear to have a loop power control. Not sure what causes this, but I'll need to test further.

MXtools is the software used to manage the radios.

MXtools Revision History.txt

MXtools V3.1.8010

MXtools V3.1.8028 - Needed for >3.6.0 Firmware.

All these need a password to program the radios, and have different access based on the password used.

  'solder' -  basic password, lowest access
  'solderall' - more advanced password
  'solderadv' - more advanced, looks like you can change the model number using this and the channels from narrow/wide
  'solderusa' - not sure
  'solderalllc' - looks to be the best

Firmware

The firmware sits on a 27C512 64k byte EPROM.
