SRI-M550 Amplified Speaker

Oct 052010

I bought this amplified communications speaker at a military surplus swap meet. It’s a nice little powered speaker which is intended for use with manpack radio sets (particularly ones with digital data capabilities). It is powered by a 9V battery which fits in a sealed compartment at the bottom of the unit. It is housed in a rugged aluminum chassis, and has a pair of clips on the back which can be used to hang the speaker from one of the “roll bar” handles which are common on these manpack sets.

Radio Receiver & Transmitter BC-1335 (SCR-619)

The BC-1335 is an FM transceiver used in late World War 2, covering 27.0 through 38.9 MHz in 120 crystal-controlled steps. It is an improved successor to the similar BC-659 radio. The transceiver operates from either 6VDC or 12VDC, supplied from an external source such as a battery pack.

I bought this TBY-4 transceiver in November, 2007 for the princely sum of $26. I plan to retore it to operation, and I’ll add more information about it here… someday. In the mean time, here are some pictures.

AN/TRC-179 "Regency Net" HF/SSB Transmitter/Receiver

The AN/TRC-179 Force Terminal is part of the “Regency Net” system, which was a radio system fielded in the 1980s. Regency Net was designed to survive the electro-magnetic pulse (EMP) from a nuclear airburst. Thus, its members are a lot more complicated than other radio systems with similar capabilities, with lots of filtering on all electrical inputs and outputs. The set covers 2.0000 to 29.9999 MHz with LSB, USB and data modes. The Regency Net members include a frequency-hopping Electronic Counter-Countermeasures (ECCM) mode. The sets can function in single-channel mode with the ECCM card removed, and they were often deployed this way to non-military users such as FEMA.

Chinese Type 102E HF Radio Set

May 032006

I bought this Chinese HF transmitter/receiver set from seller redstarradio on eBay back around March, 2005. It came as a complete new set including the manuals, spares, tools, test equipment, etc. that would normally be issued with the set, all in original packaging. It was a lot of fun to unpack a brand new complete radio set in pristine condition! The historian in me felt bad about destroying the original packaging, but I just had to play with the radio! I compromised by carefully photographing everything as I unpacked it, paying special attention to packaging methods and markings.

S-448 Communications Shelter

Motor Pool, Radio Room No Responses »

Nov 232005

I bought this S-448 communications shelter on 11/22/2005 from another military radio and vehicle collector. I plan to use it as my primary radio room at home. It originally housed a Collins AN/TSC-60(V)1 “Communication Central” set. The interior was completely stripped of equipment when the previous owner bought it, and he installed some equipment racks, desks, drawers, etc. He also re-wired it to run from single-phase power instead of three-phase power. The shelter would have originally had a panel on the right side of the door with a whole bunch of connectors and binding posts, but that has been replaced by a blank metal panel. If I need to add any external electrical connections, that would be the obvious place to do it. Some of the ventilation panels leak, but they look like they’ll be fairly easy to repair. Overall, the shelter is in good shape, and it’ll make a really nice radio shack.
