Here's the caption via Google Translate:

Photo of the E27 transceiver panel of the theme exhibition, Tianjin Electric Works No. 2 Factory, in response to the urgent needs of the volunteers, put together a 15-watt telegraph produced by the incomplete radio station in stock.

Volunteer Army radio stations are not only small in number, but also low in transmission power. Senior Cui Lun recalled, “During the campaign period, there was no condition to build a centralized station. Zhisi’s radio stations were all configured in a single station.... The radio power can only use hand-cranked motors and cannot increase the power.... Starting from the end of 1951, the establishment began. The centralized transceiver platform... After completion,... the transmission power has increased from 15 watts to 180 watts, and the work efficiency has been increased by 10 times...".

The propagation distance of short-wave electromagnetic waves and the effective communication distance are two concepts. In order to ensure smooth communication, the Volunteer Army headquarters moved forward several times, and even moved forward from Junzili to Shangganling during the fourth battle, and advanced for more than 100 kilometers to the south. Keep a distance of about 150 kilometers. The 15-watt radio is in the mountains and on the battlefield, and one of them maintains effective communication during the movement. If I hadn't personally experienced what the predecessors said, I would not dare to imagine the younger generation.

Hello All,

I was researching Chinese radios and found this photo. https://i1.kknews.cc/SIG=1hgf2uf/ctp-vzntr/8srq79sqr7rs4n16n6oqq2rq898155n8.jpg

It looks like this set used a lot of UK parts, possibly WS19 bits. From what I read, very few of these were built. It looks like they were built in the early 1950s for use by "volunteers" to fight "US aggression" in Korea.

The full article in Chinese is here. https://kknews.cc/zh-cn/military/6gn88rp.html
