And then there is the unused OFFSET knob and OFFSET SELECT switches or RIT
and XIT on other equipment which along with SPOT or ZERO BEAT were the way
to NET on CW or keep from chasing each other up or down the band on SSB.

Subject: Re: [TenTec] In praise of older technology
My experience is that with modern equipment, when people say they are on
3895 they actually are, +/- not much and they actually stay there. Land
yourself on that number and you've got it. With older equipment not so.
Without a leader that we all tune to, say in an informal gathering, we
wander all over the band. Somebody is a little high, I tune to him, maybe
miss by a little. Somebody else tunes to me, misses a little etc. And, of
course, we all drift like mad.
Even with a leader, it can be pretty amusing. I participate in a vintage
sideband roundtable most Tuesdays. We all tune to the roundtable leader.
Depending on what he's running we can end up 5 kHz from where we started if
somebody doesn't jump in and drag the whole conglomeration back. And many of
the people who have tuned to net control haven't really succeeded. Maybe the
tuned to where he used to be. Maybe they just couldn't hear what's right.
And no, people aren't very good at hitting it dead on when they are tuning
to natural speech. You can prove this to yourself. Using a dummy load and a
recording of a voice that isn't you, tune with another receiver until the
speech sounds right. Analog only. Now play some music through the
transmitter. Chances are it will sound like hell. You've missed the mark.
I've invited other people to do this. They can't hit it either. I have
theories on why this is but that's another story.

How does a digital readout help you to get on the same frequency any
better than an analog one ? If you can't hear when a human voice sounds
natural then a digital won't help.

I know. As an aficionado of vintage equipment I agree in spirt. But on
SSB it really is delightful to talk with people who are actually on
frequency, a rarity with vintage gear but the norm now with new
equipment. People just sound so much more human when their speech isn't
shifted 30 Hz or 20 or even 10.
I have a Corsair (I) and have not considered replacing the PTO with a DDS
unit but might just find a way to get a better read of my actual
frequency. Shouldn't be hard. That way I can talk with my buddies on
their Flex Radios (*), ICOM 7600's and such without annoying them while
still enjoying my fine old stuff.

* I have all that modern stuff too, an SDR, OMNI VII etc. I just don't
like it much. Heck, I think my favorites are the tube pieces from '50's.

I remember when digital frequency readouts (the kind using an electronic
counter, not the kind on a R-390) started appearing on ham gear. Most
people (myself included) just had to have it. We never needed it before.
There were easy enough reliable methods to make sure we stayed inside
our band (or sub-band) limits, but for some reason it seemed like a
digital display of our frequency became a necessity.

I guess it was a year ago I put in a DDS replacement for the PTO. Rock
solid. Dual VFOs, speed sensitive tuning, all kinds of goodies.
I took it out and the analog PTO back in.
Yep, it didn’t have the same feel. It (the DDS) made all kinds of noise
when no antenna was connected.
Sometimes, and this was one of them, older really is better
