I wonder if certain coil sets from different HROs are comparable?
==================================================

The older HRO coils will work in your HRO-7. The HRO-50 coils will
work too as will the low-frequency HRO-60 coils. It's the A and B
coils for the HRO-60 that are different. The HRO-60 is double
conversion on those bands. As far as I can tell, all the single-
conversion coils are interchangeable. I have used several different
low-frequency coil sets in my HRO-60 and they work fine. --Ed
