[Boatanchors] [ARC5] [BoatAnchors] BC-375: STABLE AM QSO on 7160 KC

[Michael Bittner]

To whoever has the dead RAK from which the detector coil was salvaged, if 
you are parting out the RAK, I am in need of the coil shields for the RAK to 
go with my set of NOS RAK-7 coils and other replacement parts for an 
eventual HB RAK.  If willing to part with these shields, please reply off 
list.  Of course, will pay any reasonable cost and shipping.  Mike, W6MAB
