Nice. What year was that photo taken?
I bought the 505, then modified the SSB Gen board, replacing the 4 crystals
filter with an XF9-B 8 pole SSB filter, which at that time was the best SSB
filter you could buy (for 9 MHz).
Then I bought a new 509, but migrated the SSB Gen board from the 505 to the
509 because of the filter.
Then I built an audio filter and mounted it inside the radio.
Finally I added a 6-pole 500 Hz Xtal filter (from Yaesu).
Kept it for 20 years and was all over Europe with it, on mountain tops and
sandy or rocky beaches.
One of my favorite portable locations was the Isle of Man.

Rick,
The 509 was a fun radio. I bought one new when my friends were buying the
TS-520 and 101E.
