HT1250 UHF1 PMUE1711B
Here are pictures of the HT1250 UHF Range 1 (403-470) PMUE1711B radio. I've removed all 16 shields in this radio and it still works :-).
The factory states this is
H25RDH9DP5 PMUE1711B PPT LS Pref nkp UHF1 11.00
This means it was a PassPort Trunking LS Limited Key Pad model. The code plug version is 11.00, but again these version numbers are not revisions, but more a collection of features.
Some pictures were taken with a microscope, others with an Iphone. I've not edited them at all. Note the a couple of the buttons (Monitor and PTT) have fallen off the board.
