Telegraph key of the radio station Angara, USSR

Telegraph key for military radio stations R-131, R-129, R-143, Glet-N and the civil Angara. The key is not convenient in the adjustment. Some round nuts have to be completely removed from the key, since with them the key can not be adjusted. Instead of a nut, put several washers. Round nuts are not convenient to unscrew or fix. If the new telegraph key has been stored for a long time, then the nuts can sour, and twisting them without the help of pliers is very problematic. If the lid is closed to the end, then there is a possibility that it will touch the manipulator. Therefore, the lid does not close completely. On the key it is not convenient to work for novice telegraphists. There are many such telegraph keys on sale. The key is fixed on the radio station behind the plate from the bottom of the case.

Connector for the cable 5D-FB

I present to your attention the connector for the cable 5D-FB. The connectors are purchased on a popular Chinese site. Since 2013. I have a 5D-FB cable. When the cable was purchased, a large search was made for the connectors. Such connectors for the 5D-FB were not on sale at all! A conventional PL-259 was used for the RG-58 cable, it was drilled in two diameters (under the central core and under the outer diameter). The photo shows the PL-259 and the 5D-FB cable. The connector remains up to now, but I would like to find a native connector. And in 2017 the connectors for 5D-FB appeared on sale. They cost 2.5 $. The 5D-FB cable is popular, for HF bands the most suitable and not expensive option. Cheaper than just REXANT (analog RG-58, but the characteristics are worse).
