[Lowfer] First Light

[Douglas Williams]

It's a great receiver for the price. When you set it to CW Reverse, you
will see "REV" in the upper left corner of the display. I put mine in
reverse mode the day I unboxed it, and it's been that way ever since. I'm
pretty sure I have a spare 500 Hz IF CW filter (Icom brand) in my closet.
The reason I have it is because I decided to go with two 250 Hz IF filters
a couple years after I bought the R75. I would be willing to let it go
cheap. E-mail me directly if interested.

I use my R75 in combination with a Todd Roberts ovenized AMRAD LF
converter. I find the combination to be easily stable enough (in the house)
for QRSS60 (slow).
