Hi guys,
   I have an R-388 (one with the filter kit installed). I started an alignment about a year ago but stopped after removing the PTO in order to correct the end points. Now I have changed my mind and just want to put it back together.
For the life of me I cannot get the PTO back in. It is running into the gear that sits behind it. Anyone recall how this goes back together?

Thanks
Rich

You do have a manual handy, correct? I never took mine out as the dial alignment was "good enough".

Yes, you need to drop the front panel to remove/install the PTO.  Angle the rear of the PTO slightly downward as you work it back in place.

The filter kit is used to add the 3 mech filter slots to an R388 -- essentially converts one to a J4 equivalent

oh yeah, that filter kit.... Cheesy

FB OM if you can find the filters and the "kit".
I let one of them slide some time back on ebay, guy was in OZ. Later he
told me that the shipping would not have been expensive, I thought it probably would have
been. Odd how it costs so much to ship FROM here and almost nothing to ship TO here.

The F500-series filters have really gone out of sight.  It can be cheaper to just buy a complete 51J4 than try and separately buy the filter unit and filters one at a time.  Makes no sense ...

There is a 51j-4 on ebay with the filters.

I was able to acquire some 500kHz filters a few years back, but have not implemented them yet.

The other solution is to use the R-388 as a tunable front end and then run the IF out into an I/Q Softrock type interface and use SDR software... I like this idea, and similarly have not implemented it yet. Sad

<joke> all my assistants were picked up and deported, that's my excuse </joke>
