I've seen HRO's for less than $50.00 at hamfest without coils! The VLF
coil might be hard to find but you'd end up with less stuff and less work!

Hi Hank. You're right, but I've never seen a set of LF coils for the HRO
despite seeing (and owning) several HRO's. Then you need to factor in the
expense of the additional room you have to build to house the thing, seems
terribly expensive to go to all that trouble to replace a DBM, a low pass
filter and a one transistor crystal oscillator to build an up converter. Use
whatever you've got for the IF.
