Rx Green LED replacement

Post by 9M2IBR » Wed Oct 07, 2020 11:56 am

Hi all

I just got my 2nd DM1801. Unfortunately, the RX led is very dim. Anybody know how to replace this LED and what type of Smd LED used in DM1801.

Is the problem the LED or the light-pipe

I recall problems on some radios where the plastic light-pipe was not in contact the the LED, hence not all light was transferred to the outside of the radio.

I can't recall a solution, but you could look on the VK7ZJA GD-77 Mods page to see if a similar problem exists on the GD-77 and whether this is a fix

It LED problem. I already tear down the HT. Green LED is significantly dim than red LED.
