[HBR] HBR Tuning Cap, Coil Forms

[Byron Tatum]

Hello Darrell,
    Thank you for the nice note. I will check out the forms from OSE.
    Your idea on modifying a capacitor on hand is a good one.
    I still want to build the receiver shown in the Orr HB, " DX Receiver"
that uses a xtal. controlled first LO and a tunable IF second conversion. I
have another front panel / subchassis all layed out for this one, having
trouble finding the JW Miller RF coils of B-727 variety, do you know of a
good source for the older JW Miller parts?
    Take care, Byron.
