I notice something interesting about this radio. Their are terminal for
6 meters. Throughout the last 10 years when I had scanned the 6 meters
on my scanner, I do not think I had never picked up any hams. (BTW I am
in the New York City area) Yes it is a very short band and it might be
more related to 2 meters, I would think.

So why would Hammarlund go through the effort to add terminals on the
rear of this radio. My only guess is that at the time hams were using
the 6 meters a lot more.

Also, this radio does not seem to pick up much on the 21-21.6 and 28-30
bands.

I have a reprint copy of the manual. I was reading the part of the SEND
RECEIVE CAL button. And somehow this has something to do with something
called BREAK-IN RELAY. (There is a relay female chassis connector at
the rear.)

Because of this can this radio make some kind of transmission?

Could someone please explain this to me in layman terms.

BTW I love the radio!

Thank you, SR!

what the (A) stands for or what is the differences in these models.

The radio is big and it works. I do not have any instructions for it
yet. But I was able to buy a manual, which should come to me sometime
soon.

The radio is very sensitive. And it has no speaker. I am using a small
speaker and sometimes headphones. Sometimes it can over power the
speaker and headphones

When I pick up a signal, say a voice, it does not sound as clear. The
sound need to be better clarified. Although I play around with the
buttons, and try to figure out how to better tune in a signal.

The radio has no volume button, so I use the NOISE LIMITER button and RF
botton to adjust the volume acordingly.

There is a AF button but I am not sure what it does. When I bring it up
the signal get stronger.

There is a ANTENNA button, I guess that works like a antenna turner.
Which I also use the MFJ 956. I wonder if I could use them both?

I am not sure what the SLOT/FREG and the SLOT DEPTH buttons are for.

The radio has a few terminal screws in the rear. (A, A, G, 6m and SPKR)
I have two alagator clips on A and A and to a PL 259 coax connector then
too my MFJ 956 tuner then to my antenna switcher then to my homebrew 90
feet coil dipole or to my 8 foot fiberglass whip.

I have the G (I guess this is for gound), on a clamp and to my radiator
pipe.

6m must be for the 50 MHZ! VHF

SPKR is this for 2 speakers or 1?

I plan to find a way to add a rear female coax connector to the back of
the radio so I could better connect it to a PL259 coax.

I wonder if their is a way to add a frequency counter to this radio?

Their is one button missing. Their is a small piece of metal sticking
out under the clock. Is their a way I could set the clock?

Behind the clock their is a rod in the inside and it reaches the back
with a hole. Maybe that is the way to set the clock. Their is another
hole like that on the other side on the SLOT FREQ side. But I do not
see a rod behind it. It their suppose to be one?

Also I notice a few holes in the back and inside a plasic you can turn
with a scew driver. Not sure what that is for.

I hope I could find extra tubes and fused should I ever need them.

And I wonder how others who have this radio feel about it?

73, SR!
