My father gave me a Heathkit SB 610. I am not sure what it is for. I
have no instructions and my father doesn't talk much.

Is it for monitoring incoming signals?

It has lots of buttons. I notice I could control this light green line.

It has two openings for the Pl 259 coax. It it for radio and antenna?

It's a cool looking thing. But still, help!

Yes...

and

WWW.Eham.net if you want to sell it.

It's a panadaptor, ie a specialized and limited form of a spectrum analyzer.
It's a full receiver, which is continuously tuned by a ramp generator feeding
a varactor that tunes the local oscillator. The output of the detector in
this "receiver" then feeds the built in oscilliscope. So on the horizontal
axis you see frequency, and the vertical axis shows amplitude. In effect
you get a picture of the signals being seen by the unit.

It tunes a fixed range, I think of 500KHz. It's hooked up to the output
of the first mixer of your receiver. At that point, the receiver's
selectivity is broad, so it won't affect operation of the panadaptor.
As you tune the receiver, it shifts the center of what the panadaptor
is viewing (and showing). So if you tune the receiver to 10MHz,
the panadaptor will be showing what's on either side of that frequency,
out to 250KHz above and below, and as you tune up in frequency the center
frequency of the panadaptor will go up, but you will continue to see
what's above and below that center frequency.

The SB610 was a kit, and it came with information and parts to allow
for use with different IF frequencies in the receiver. So you'd have
to know that before you built the panadaptor, and now you'll have
to figure out what it was built for, and if it doesn't match
your receiver IF, track down the needed parts.

I never heard of a panadapter before untill you mentioned it in this
thread.I just now did a www.devilfinder.com search for,Panadapter
Radio Kits.There is some information there.About ten months ago at the
Goodwill store I bought a Young World Base Station Transceiver radio for
two dollars.A label on the back of the radio says,F.C.C.Identification
Data.Young World.Midland International Corp.Goodwin Division.1900
Johnson Drive at State Line Road.Shawnee Mission,Kansas 66205 Model NO
91-070 This Device Complies With F.C.C.Rules Part -15 AS Of Date OF
Manufacture OCT 1976 Taiwan.There is jack on the back of the radio for
DC 9 Volts.On the front of the radio is a large dial and knob and a
small on/off/volume control knob.The dial shows that the radio tunes
from 26.965 to 27.255 frequency and there is a telescoping antenna on
top of the radio.At the bottom of the speaker grill on the front of the
radio is a large red rectangular shaped lever that says,PUSH TO TALK.I
removed the back panel of the radio (which is very easy to do,there are
two finger holes,just ease the rear panel off and it's off) and there is
a plastic battery holder that looks like it takes six C cell batteries.I
think it is a Transceiver radio intended for children to use.I don't
know if the radio works or not because I haven't gotten around yet to
putting some batteries in the radio.Any comments about the radio?
