Hi Harold
My way is travelling a random path and finding whatever is fast, cheap
and available because if I look too long the urge soon goes away. There
are too many distractions along the path, and at times create a greater
urge. So one has to drop the lesser urge and pursue the greater urge.
It too, can be sidelined.
Another options is a frequency selective voltmeter, they used to be real
cheap but now not so because I think the VLFers have their eyes on them.
I still see the odd one at hamfests for about $20.00.
Yes I agree that a transistor osc. or a 6BE6 would do the trick.
I kept one HRO for sentimental reasons and to waste gravity and
somewhere in a box I have stored some odd ball coils. I'll have to see
if I have LF. I might because interest in LF and VLF is one of my
chronic diseases that is currently in remission.

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.
