Never heard of that ?? Where is the page/htm/pdf ??

Never heard myself ! This is just a wish... ;-)

I think it might be too complicated to implement.

Did you do any mod's to either?



Nothing yet. There seem to be some trade-offs involved in most of the
modifications. If the customization bug ever hits, I still have a spare,
stock radio to fall back on. I have adapted a stereo jack for the
external antenna port that overrides the built in AM ferrite rod. It's
an easy external change.

I did the whip antenna matching transformer (balun) mod' to my 398. It
really helped to make it more sensitive on the whip. I also removed the
tuning knob detent mechanism to make the knob turn smoothly.

Hello all,

The best mod on the 909/DX398 could be adding the Sync detect. I have a
909 and a Sony SW100. I usually prefer the 909 for the general listening
and "browsing" the SW. When I have two stations on the same frequency, I
then try the SW100 with Sync. It helps...

Does anyone knows wether this is possible ?

Charly

Possible but not practical. AFAIK it hasn't been done.

Is there any problem with maintaining a setting? I was wondering whether
there is sufficient friction remaining to keep the knob in a particular
place.

I haven't noticed any problem with the tuning knob moving on it's own,
since I defeated the detent system. It turns much smoother but still has
some resistance. I suppose it could be accidentally moved if it came in
contact with something. This might happen when the receiver is laying
down on a soft cushioned surface like some furniture but I wouldn't be
concerned about it. The tuning knob has a much better feel without the
detents.
