Re: [Drakelist] Using a Drake 2NT and Drake 2B on 30m

Steve,

My experience with other tube rigs (and tuners) being used on 30M is that
sometimes the tuned circuits do indeed swing far enough (from either 20M or
40M positions).  However, the Q is always wrong and you either end up
either too sharp or too shallow.  Best to leverage the higher band (20M)
and switch in some additional capacitance with a relay.  It will be easy to
back out that mod later with no traces.

[Drakelist] Using a Drake 2NT and Drake 2B on 30m

[Steve Ireland]

G’day

I’ve got a Drake 2NT and 2B, which am in the process of refurbishing.  With the 
decline in solar activity, I was wondering if anyone had found ways to use them 
on the 30 m band?

Maybe the 2B just needs relatively straightforward crystal addition, but the 
2NT looks like an extra coil would need switching into the anode circuitry of 
the 12BY7A and potentially another tap put in place on the 6HF5 PA tank coil 
(am wondering if the 7MHz or 14MHz tank coil tap would tune there?).

Any information would be much appreciated.
