[ARC5] 10 meter BC-454 - another bit of news.

[D C _Mac_ Macdonald]

Unfortunately, my 1.5-3.0 from the old days went to the 
dump along with a beautiful BC-221 and LM-323 after a 
tornado took the house in 1999 and I didn't have the 
storage space to keep them.  All my logs from day 1 
as a ham went also. 
 
I did acquire a very nice CBY-46104 with only the usual 
hacks (BFO switch, Vol, and LIM switch) on the little 
front panel, six-pin amphenol for power at the rear, 
and pin jacks for headphones. Exterior is very primo. 
 
I may get to it some day, but with a new Icom IC-7410 
and no real work space, the impetus is pretty low!
