应该在天线端也测试一下

这机器好似泉州出品公模机，uv20差不多了

@"BG4QBF"#p98396 买的时候觉得UI界面算是比较好的，用到现在就是发热的问题比较严重

@"BG0EWT"#p98399 可能不如kt8900。不过8900没有好的屏幕和UI。

iradio UV2520 Car Radio UV Band Transmission Power and Antenna VSWR Test

BG0EWT

The antenna is a Renqiu Tianyue 2.4-meter dual-band UV double-segment glass steel antenna.
The standing wave ratio for U-segment is 1.3, and for V-segment it is 1.2.
The machine is set to high power transmission, with a displayed transmission power of 20W.

The following is the UV segment standing wave comparison test.

The following are the results of the transmit power test.

The following are antennas.

BG0EWT

It should also be tested at the antenna end.

BG4QBF

This machine seems to be similar to a model produced in Quanzhou, and its UV output is approximately equivalent to that of UV20.

BG0EWT

BG4QBF When I bought it, I thought the user interface was pretty good. However, the biggest problem I've encountered since then is excessive heat generation.

BG4QBF

BG0EWT It might not be as good as the KT8900. However, the 8900 lacks a good screen and UI.
