[Hammarlund] SP-600

[Bob Young]

I'm out in Peru and the link didn't work for me a few days ago but I just saw it, it looks to be in pretty nice condition with a few minor mods. I wonder how these compare to R-389's as far as receiving sensitivity? I like cruising the low bands, when i was last doing it I had a 1000 ft dipole set up in the woods. I wonder how high it will go, hopefully it goes to someone here.

Interesting. Always wanted to find a "VLF" to add to the collection, but a little pricey for me.
BNC and mini toggle look to be add ons to me. BNC is not wired and the toggle looks like it controls the dial lighting. Someone added an SO-239 connector. No xtals or tube in the aux xtal unit.
Looks to be in good condition - I need to think about this one.........

Les,
This radio has many mysteries.  The tuning/band change knobs made me think of the 21A.  The dial faces seem unusually white. Note the non standard toggle switch near the meter.  The BNC connector seems to be from the factory as it is connected by the panel paint.  Many screw heads seem non standard.  Yes the tuning lock is missing but it could be replaced from a "parts" SP-600.  Is the meter face non standard?  Why would the nomenclature tag be wiped or never filled out?
This mystery radio seems to be a very late "one off" of some type,

The tuning lock knob is missing, possibly the locking mechanism behind it. A bnc connector on the RH top front panel that goes where? And the nomenclature tag on top of the tuning condenser cover seems to have been scuffed up and is unreadable. The IEC type computer power cord isn't original...etc. Ya pays your money and ya takes your chances.
