Yup, but I will have to go and snap those picture. Antennae are in the garage right now.

Teotwaki:
My PRC-117D was good for talking Satcom but I've sold off the radio and some accessories I listed here. I need to move the rest of it along.
There is a short video of it receiving Brazilian pirates.

Very nice on the radio. I used to own one of these as well. I have pretty much sold all of my tactical VHF radios other than my pair of SINCGARS. I had one of them mounted in the HMMWV. I sold the vehicle a little over a month ago but kept the radio and accessories.

Teotwaki:
I got my fill of both SINCGARS and HMMWV acronyms back in 1989-1990 when I set up two of the radios in this Hummer. I think it's the right picture... Well before DARPA started having self-driving UGV contests.



It was the Army's first Unmanned Ground Vehicle that was operated with a heck of an onboard electronics suite:
 
Day/night passive-perception sensors (visible, infrared, multispectral)  test algorithms such as iris control, real-time stereo ranging, obstacle detection, path planning, path following, velocity control, gaze control, and terrain classification.

The computing system included several VME single-board computers operating under the VxWorks real-time operating system. The HMMWV wais equipped with a NovAtel RT20 differential global positioning system (DGPS) receiver, which yielded a 20-cm horizontal circular-error-probable (CEP) accurate positioning solution at 10 Hz. It also contained a Honeywell Modular Azimuth Positioning System (MAPS), an inertial navigation system (INS) that produces position, orientation, and velocity data at 25 Hz. The INS and DGPS solutions were integrated with an external Kalman filter. A 5-kW propane generator, housed in a side panel, provided power for all onboard sensors and computing hardware. The SINCGARS standard data handling was used for the radio modem aspects of the vehicle build.

The Hummer may have gone to an active sandbox for a test but who knows for sure. After all that I had no interest in owning a SINCGARS or a HMMWV, lol. These days AN/PRC152A radios are more fun and I don't have to pay for them..

Teotwaki:
Brazilian pirates are getting chatty this morning.
