Thanks for all the input.

One last question, (I swear) Heathkit Seneca 120 watts On AM. Good, no good, OK with modifications?

Thanks, RSWL

The 120 watts is input power. You could probably get about 40 watts peak on 2 meters and maybe 75 or 80 watts peak on 6 meters. The modulation was carrier-controlled. Also suffered from lots of drift and even more so on 2 meters. Cabinet designed to match the Apache/Mohawk and similar boxes of the era.

The Seneca reminds me of a 2/3 scale Apache. The mod scheme is similar to the DX-60, etc. It could be modified in a similar manner and sound fantastic. I wish I still had my Seneca.

Swan 250's, and even the 250C's, are well known for their drifty oscillators. Set the receiver at one location and  signals will just drift on by.
Ah, yes.....the good ol' Swan TooDrifty. Just wait a few minutes, it might drift back by. Even in a time when some drift was still expected and tolerated, this thing was pretty marginal.

As to the Seneca, WA2PJP who is a member here has one that he rebuilt from the ground up, addressing any issues along the way. He'd be a good one to talk with for anyone considering setting one up. Not a bad set from the little I've seen. Definitely better than a Sixer!
