Background
This came from Murphy's Surplus (eBay store).
Datron used to make the PRC-1077 that was their backpack version of the PRC-77 VHF low band FM radio. This HH1077 is a Hand Held version of the PRC-1077. It is part of their SPECTRE V product line.
This radio kit was part of the Foreign Military Sales (Wiki) to a country with the FMS code of "QB"sponsered by the Defense Logistics Agency (DLA) (FMS code "B".
Four years ago, i.e. July 2021.

Accessories Not Supplied
HH-3900BAT Battery
This makes a problem in powering the radio.
Programming Cable & Software
This is a problem as these are needed in order to set the frequency and other parameters for each of the 15 channels.
You can not set the frequency of the radio using just the radio.
DC Power
The minimum DC voltage is just below 5 Volts. Radio beeps if battery is <6.5V.
The current v. voltage does not look like a linear supply (power goes up with voltage) and does not look like a pure switching supply (power constant with supply voltage change). Any thoughts? let me know.
On Tx the current draw at 8V is about 2 Amps. The Agilent E3617A is rated for 0-60 V 0-1A so failed when Tx was pressed.
The HP 6038A rated for 60V & 10A works well.

Controls
These work like a Japanese watch. That's so say combination presses have various functions also short and long presses have different functions.
