[INRAD] [1000mp] INRAD 2.8 Filter Install Gone Bad

[Hans Remeeus]

Hello Bob,

To prevent these problems it is wise to install the Inrad 2.8 kHz/455 
kHz in place of the OEM-filter.

I did this in my Mark-V and FT-1000D and it really looks more difficult 
than it is!

Just pull out the two flat cables and the one coaxcable at their side. 
You don't have to remove any other cable.
Afterwards just flip the board over.

Have a look at this photo:

De-solder the OEM-filter with an enough hot solder iron; let's say 350C 
degrees. And use thin de-soldering braid (litze) size 075 e.g. from 
Chemtronics

It really is quite simple and you will definitely get the best results 
(RX and TX)!

Good luck and always willing to help you.
