The only problem with inexpensive RFs like Heath (2-tube types, ECC82/12AU7 based) is at least at lower frequencies their wave shape is quite a bit away from sine wave (it's not the oscillator itself, it is the follower that does it).

Like so.

And somehow SG-8 will not generate at the lower part of E-band (I think about 26-27MHz).
And they are not precise so you need a counter which is.

I acquired a Leader LSG-11 (same schematic mostly) and two SG-8 both of which I revived this last week and they behave the same, only Leader is actually precise (except the C band somehow is off).

If you chose to get a counter, I got my BK for 25 bucks and it is very accurate and worked right off the start (did not get to do anything to it).

Like this one (I also have the Dynascan but for higher frequency - however this one is enough for AM work. Whether it works or not - I took a leap of faith considering my price was the same).
