It's not easy, and without a meter it's not accurate just by
listening to the signal to noise ratio, with signal down in the
noise!!
Incidently, ALWAYS use a 20,000 ohm resistor in series with the 50
microamp meter used to tune it up. The test set uses the resistor
built in.

It's easier to build one rather that to buy, partiularly on
an auction, but using without removable adapter cords!!
