Generic DVR
I had a LiView that blew its main "CPU" due to heat.
User 0909bestchoise refuses to resolve despite their "3 YEAR Warranty".
For around $30 you can buy the CPU/GPU chip; instead, I bought this unit which was about double the same price of a new Hi3520 DRQCV200 chip.
Before using, I opened the case and found the exact same board/Hi3520 as the LiView; unprotected.
I placed a heat-sink on the "overheating chip" and brushless CPU fan inside before use and have no problems with rebooting now.
Basically, for use in an air-conditioned room without modifications or it will fail.

LCD COG Backlight
This is the backlight for the I2C COG LCD Displays used in our KX 170/175 Beez Digital Conversion, should you ever need to replace it. Use slight heat to remove the original "glue"...

1MHz to 1000MHz RF Frequency Counter Tester Meter Digital LED
At first, I had to figure out how to use this thing without shielding.
I have read that it is inaccurate at higher frequencies; but, in my experience with this unit in the VHF spectrum, I have found to exceed the accuracy of much higher costing "professional equipment"!
I operated mine at 5-1 to 5.3 VDC as the input (power) has the 7505 regulator.
Rule of thumb, buy an equipment where you desire half-scale usage.
This rule fit my need on this unit and I am extremely pleased with it.
In my use, I leave it on High-Frequency; use the lower right button to "fine view".
Mine is the 8-digit unit.
For an antenna RF counter, just wrap a few turns of the RF input wire around it.
