I had a 520 SE (520 S Economy) for 14 years.

520 was 5 band and 120 vac or 12 vdc
520 S had 160 meters
520 SE had 160, did not have 12 volt.

It did not have the 12 volt input, so it did not need a heater switch. In
place of the heater switch was a wide / narrow switch to let you run the ssb
or cw filter when in the cw position. ( I rewired mine to allow either
filter in any mode, and used the cw filter for rtty). It did have four
fixed crystal postions, I put in two crystals for Packet Radio frequencies.

A word of warning. Actually 2.

The coils in the bottom are a tinkerers delight and many radios have
broken
cores. The coils are not available. The most tinkered with was the 10m
coil.
If it is broken the rest of the coils will not align correctly.

Also the 2 relays used in it are NLA.

Other than that great radios. The SE was a 120v only version and didn't
have
the fixed freq xtal positions. There are a couple of other differences
but
they don't come to mind at the moment.

I've seen some of these (only on the net) and have become interested
in
maybe purchasing one in the future.

My question is: which model is the best? Other than the fact that the
520
has no 160m band (I believe this is correct), what are other
differences?

Thanks!
David
