This is a low power system that has the same RF output as the RT-1319. The AM-7217 is an audio amplifier (no RF function).
Notice that the antenna is
connected to the RT-1319 not the AM-7217 audio amp. The space to the right it for an optional KY-57. |
|
Inside the travel case are: RT-1319 AM-7217 Audio Amp - AC mains or vehicle DC Power Supply Storage compartments. On top of the case are headphones, an H-250 handset and something similar to the MX-211 remote called the Remote Set Control C-11165. |
The top and bottom covers
for the travel case have storage spaces for a number of
cables, the donkey dick antenna and other accessories. The audio amp/power supply does not appear to have any RF amplification capability and that's consistent with other similar military units. |

I did not see a JTAG (Wiki) connector inside. The connection between the front panel and main chassis is via a black 2xn type header, but it's not JTAG.

remote Got this also as a possible source of spare parts. It's OFF-Volume switch has nice clicks going off and coming on. It also appears to be the same size and has the same markings as the one in the stripped chassis. The labels on the keypad of this remote, the stripped chassis above and the RT-1319B are all the same. I think that means that they are for version A or B, but not the no change UHF AM aircraft radios (without Have Quick). The artistic pattern shown on the LCD is not a reflection, it's the LCD pealing internally. This happened to early LCD panels for a year or two because they were not well sealed. Note: MX- means Magnavox Special |

The remote used with the
TRC-176 has the Audio connector on the front panel (where
the hole filler is in the lower left corner above). The note "HV supply removed 12 Jun 99" is referring to the high voltage module used for back lighting the keypad. The connector on the box is a MS 3112E14-19P w/ date code 8417 |
