You may recall my recent posts while I tried to decide which tabletop
reviever to buy.

I found a Kenwood R-1000 on eBay so I decised to buy it. Cost me
US 287.00.

As far as I can tell, it appears to be in very good condition. Smooth,
postive action on the knobs and switches.

I can,t revieve anything above the 11 meter band but I never could
so I don,t think it a fault in the radio. I could be wrong but I
don't think so.
I only using an indoor (on an inside wall) random wire antenna. I
need to set up a good outdoor ant.

My question is on the antenna connection points on the radio.
There are SW A and B connectins and a MW connection. The manual
says that an antenna should be connected to MW for freqs under 2mHz
and to use the SW connection for freqs avove 2mHz.

I find very little improvement by using the SW connections for any
freq.
I find great improvement when using the MW connection all the way up
to the 11 meter band. This is not how the manual says it should be.

Is this normal? Is the manual wrong or is there a maybe a fault in
the antenna connect points on the radio?

Can I connect the same antenna to both the SW and MW points at the
same time. That would basically be jumping one to the other.

What's with the dial calibration ring. There's nothing to calibrate,
it's just a log scale (I think).

Answers to those couple of questions would bring me inline with what
appears to be a fine radio.

Thanks,

There's the switch on the back panel for which shortwave antenna is
in use. It matters.

Somebody could have been irritated enough that they changed the antenna
wiring around. (It's all there on the back panel. Turn the radio upside
down and take off the bottom plate...). Playing around with antennas
and then forgetting the switch setting is a common problem with us
R-1000 owners.

There's the Coax connector for the shortwave, it's 50 ohms (nominal).
This is what you'd use for a resonant antenna, or for a "tranformer
at the other end of the coax" Quiet Antenna connection. The speaker
(Fanhestock) clip for the wire antenna has a built in tranformer to
make that input 500 ohms. 2 MHz and below use the other speaker clip
wire, it also has a seperate matching transformer.

There's a high value (10k ohm) resistor already in there to make
a connection between the two antenna. So medium wave will work
(poorly) off either of the other two connections.

Frankly, it's pretty deaf below 2 MHz. In addition to the seperate input
circuits (with the strange input impedance) for below 2 MHz, there's a
gain spoiler circuit that cuts the sensitivity down to 50 microvolts.

What's with the dial calibration ring. There's nothing to calibrate,
it's just a log scale (I think).

On mine it's a chem etched metal dial plate for the 1 MHz of the VFO, with
10 kHz hash marks and every 100 kHz in text. If it's not lighting up
(green), you've got a dead grain of wheat bulb. (The other two lamps
(meter, bandwidth) in mine burnt out and are replaced with amber
LED/resistors, but the main dial lamps never gone out in mine, so I
don't know the replacement procedure).
