That would be called "bandspread" as I remember from my old S-38B.

Yep...it would be terrible to have to use a logging scale to be able to
find ones net....
Ha...

That's exactly why I purchased an amp that uses a single 3-500ZG.
Within the past 60 days I've had 10 radios across the bench and from
different brands/models. Although the frequency display seemed very
precise, none were correct and some were off as much as 200 Hz. The
most accurate was +2Hz on 75M but progressively got worse as the
frequency increased to 6M.
I have one coming in next week that is reported to be 70 Hz high on 75M.
Oh my, what a crisis.

Wade, the problem with your strategy is, you can't get "good" new tubes
anymore.
The last good source for 572B's ceased producing them a while back and
RF-Parts temporarily removed the tube from its sales.
Apparently they have found a new source now, but each time they have
had to
do that, the tubes were worse than those from their previous supplier.
BTW, did you ever solve that 30 Hz problem? ;-)

*Please, build that Tube Type Rig!..... I can see the Appliance
Operators
pulling their hair out as I write this message. I had a young fellow on
a
State Wide Net, recently tell me that my station was 20 Hz low in
frequency.
And my understanding was that Net Control is the frequency standard to
tune
to! Reading my Net Preamble again, pointing out the part that says on
or
about 3xxx KHz. We also expressed thanks to him for telling me that, my
33
year old Paragon is only 20 Hz out of alignment. Checking further that
day,
with good test equipment, maybe his KenYaeCom needs some attention. And
we
know several folks who could never Tune Up any Tube Type rig. I can see
the
Magical Mushroom Clouds of Smoke .... Screaming towards the Ceiling in
their
Shacks ..... * *Please, build us some nice radios. I have just enough
time
left to own another great station before assuming room temperature. We
can
only wonder what the guy mentioned above, would have said about my (
built
by me
) Heathkit SB-101. Maybe, we will call the Net next time with the
SB-101 and
it turned on cold. Just my Rant for the day. My vote would be for a
Modular
Approach. What radio will even nail down another SSB rig as 20 Hertz
off
frequency? Hey, here is an idea, what about a new Hybrid Rig?
Beats the pants off these badly needed 50 volt Finals in the new rigs.
My
vote is for a conservatively rated 200 Watt radio with One 572B Tube as
the
PA. The old Hybrids sure do a Great Job....... hi hi ...........*

There are as many wishes for what a panadapter should be and how it
should be used as there are hams in the market. They fall into a few
main classes though (and no, I'm not ranking classes, just
identifying, geesh, don't shoot me. and yes, I'm glad my name is John
Henry, he he he DJ0IP, lol) Don't cut down the need for something that
is a tantamount feature for someone else. Just different is all. If
there was a one size fits all, then would it be a Wyndam antenna or a
Yagi or something from those Spidery people? Or is it a Begali or one
of those from Mr. Robbins? Come on, pick one, you can't have anything
else. See, one shoe does not fit all.
There are those that will never use it, because they just want to
"surf the web", er, uh, "surf the air" to find someone popping out,
the way it has been done for many many decades. Nothing wrong with
this, so, let them have their rig, at the cost appropriate for that
rig.
There are those that just want something running real time on the rig,
no real features, maybe a gain adjustment, but they want it on the rig
so that when they take it with them, it is still there, e.g. Field
Day. So, maybe it is an option to the rig of the "surf the air" user.
There are those that want a bit more functionality on the rig with the
sweep, e.g. scrolling to the freq they want to see without moving the
VFO, then hitting an Enter button, boom, they are there.
There are those that want it as a display option of the rig, like a
panadapter such as the P3. It works great with the K3, KX3, and the
frequency readouts track. Works well with others, only drawback is you
lose the scrolling on the panadapter / click button to control the
rig. But, that too is sufficient for hams, they see the band, and can
move there quickly with the rig controls, be it on a PC or on the
front panel. Again, another option.
There are those that will never give up the SDR to the sound card
running their favorite HPSDR/PowerSDR-IF/etc. In my mind, that is the
ultimate integration giving one the flexibility because they can pick
the $39 SDR or the $5k SDR to give them the performance they want that
makes them happy.
Just provide the I/Q or IF output, and let this guy enjoy his world.
To me, IF output should be standard anyway on any rig produced...
well, maybe not down into the 506 cost range, but heck, 9MHz IF is on
the 506 anyway, just solder a wire, put in a buffer amp, and boom, you
have a band sweep from your $200 QRP rig, fun fun fun to some.
YOUR usage pattern is different from others and you may want something
different than their neighbor or cousin or even XYL.
So, concentrate on what you like about which one you like the best,
bring up the reason why you like it best, and be happy that your XYL
can disconnect your SDR and use it on the front panel as she / he
wants it when they are on the rig.
TEN-TEC has to find a happy medium, or provide options for all of the
above.
If TEN-TEC is to satisfy the guy who wants it built into the Orion
III, then TEN-TEC has to finish the 588 sweep board to prove the
concept and then migrate it into the "next big TEN-TEC rig".
For now, get the rig you want that we have, enjoy it, and rest assured
that over time, maybe next year or the next, who knows what you will
see on the market from TEN-TEC or our competitors. We all make great
stuff that fills the shack of amateur operators. For me, the main
reason for this is still to just have fun, AND to be ready to assist
others in emergency situations.
I still think there is a market for a totally analog rig, no uP, no
features other than mode/band/frequency/rfgain/afgain, the backup for
the EMP, that also means no transistors... hmmm cost, well, probably
prohibitive, but, I still wish there was a way for that rig to be made
as it would fill just about every prepper/emergency management hams
shack and sit in the background covered in dust until everything else
is non-functional.
TEN-TEC IS working on things that will tread new ground, and lead the
way in innovation in this market, and those will come out over time
over this year, next year and beyond. We are also working on things
customers have asked for, but maybe not in the way they originally
thought, but, well, better. Plant a seed, and in time it will grow.
Working on things customers haven't asked for but once we get it out,
they will wonder, what they ever did without it.... etc.
'nuff said, lots of code to write, projects to continue, etc.
Thanks, and 73,
