RIP Panadapter

So I got the panadapter installed correctly.  But maybe I did something wrong, who knows.  Maybe it just wasn’t designed to work with my radio, but I can’t imagine that it wouldn’t work.  To be fair, THE PANADAPTER WORKS!  I have no doubt that the design was solid.

Unfortunately, the panadapter most definitely caused major desensitization on my receiver.  On the order of 6db reductions on some bands.  Given what I heard regarding conditions in Rwanda, I believe that 6db reduction in reception would be catastrophic for my DX efforts.  I left the panadapter in the radio, but clipped off the wires and removed them.  I may revisit the project at another date, but for now, its unfortunate that I had to get rid of it.  Many thanks to the guys at HupRF for their expertise.  Perhaps I’ll revisit it at a later date.

The Panadapter is installed!!!

Thanks to some help from a friend who builds satellites, and has a much steadier hand than I do, the panadapter from HupRF is installed. img_20161020_182715

Some thoughts for anyone installing this on an FT-991.  First, its on the bottom, not the top (mistake one, but nothing critical) looks like the internal tuner board is on the top of the radio.  The IF is on the bottom.

Its hard to really see the scale in these photos. But the components are extremely close together, and very small.  Each soldered connection looks like its the size of a pinhead.

I did learn a neat trick from him. Don’t bother stripping insulation from a very thin wire when its a lot easier and more precise to just burn it off and clean your iron afterwards.

Also, specific to the FT-991, the back of this radio is really tight, you’ll either have to run the SMA cable out a vent hole in the back, or drill a hole thru the top if you want a mount that is really secure.  Right now, I took the SMA cable and tied a loop to keep it from getting pulled out.

I’ll add another post in the next few days to let everyone know how it works on the air.  I still need to figure out the best SDR software to display as a panadapter, and to see if i can get it to work with my android tablet.
