[1000mp] Selecting CW filter - no RX

[Zoli Pitman HA1AG]

Hi Rich,

Possible culprits:


- the switching diodes do not get the DC to switch over. - I consider this the most likely as you say none of  your filters switch in. 

- you have damaged the IF board when swapping or inserting filters. It is a big board and has no support in the middle while you have to press the filters with relatively large force and the board is flexible. It is adviseable to place a piece of plastic beneath the center of the board. 
- the small filter panel has developed an error (cold soldering)

Just a question: do the leds of the filter selection buttons on the front plate lit up accordingly as you select the filters? Do U get the beep ? (just to check if your control board is healthy - at least to some extent)

I have an interesting problem with one of my FT-1000MP Mrk V's.   When I am in CW and select the NOR filter all is well for receiving.  When I select NAR1 or NAR2 there is no receive.  Im using a signal generator and 50uv I have S9 on 20 meters with the NOR filter selected.  With NAR1 or NAR2, there is no signal. With 100uv I can just barely hear something in the receiver.

I already changed out the filters and still no RX.  I also confirmed the menu setting as this was working a few weeks ago when I last used it.

Any thoughts?

Thanks...Rich
