[Boatanchors] BC-1004

[k8wbl at wb8nut.com]

Hello Phil, Al is correct as usual, I will add that that the Hammarlund
SP-200 and SP-400 are very close as well.  I have both an SP-400 and a
BC-779, identical expect for slight variations in the band coverage.  The
BC-779 is a parts chasis and if you are looking for something, let me know
if I can help....I will also ask of the group that I am still looking for
a power supply for my SP-400, have none at present, would love to have
one, dead or otherwise... 73  Tim  K8WBL

 hi agn Phil,
>     As I'm sure you are aware, the BC-1004 is pretty much the same as the
> BC-779, -774, and R-129, (SP-200 series) except for band coverage.
> Probably closest to the BC-779 where it's only different in the lowest 2
> bands' freq. coverage, 540 - 1160kc, and 1160 - 2500kc for the 1004 vs
> 100 - 200kc and 200 -400kc in the 779.
>     They're covered in T.O. 31R1-3BC779-1  (TM11-866), which is avaliable
> for free download on The Hammarlund Historian website's "Manual" section.
> (thanks to John, K5MO, for the scanning chores)
>     There's also a reburbishment page on the BC-779 in the "Service"
> section.  I don't remember any particular "gotchas" in it, but all the

>> Hi All,
