Summary:

MILITARY:
Here we list radios and other military communications equipment that has produced not only by one but by several companies under contracts.

History:
In many cases, You cannot simply identify the maker from a logo, sometimes, the model information tag carries the name of the maker.
Many sets carry a number / letter designation. In cases a set carries an individual designation number (for example BC-348), You will use this as model type and the designation of the complete wireless station (for example SCR-287) as model name.
From many models, there exist different variants with individual suffix letters (for example BC-348-P). We list here (MILITARY) the generic model with -(*) as suffix, with the asterisk standing for different suffix letters (for example BC-348-(*)).
Please consider using "Commercial receiver" for receiving equipment, "Transmitter" or "Transmitter / Receiver" for transmitting equipment, "Repair equipment" or "Military equipment" for other telecommunications equipment for military use.
There will be military equipment with a maker, that can be easily identified or that is only produced by one single company. You might consider searching for these sets in the complete radiomuseum.org database and upload these sets under the producing company.
In case there is an existing entry in rm.org database for a model unter a different brand, please make a remark or a link in the "remarks" field, to cross-link the relevant model pages.
In case, there is a huge number of different variants of a model, consider a text forum entry with explanations to show and explain the differences.
