K3 and Heathkit SB-610 monitor scope

[K2QI]

Hello group,

I'm not very familiar with using monitor scopes, so please bear with me.
I'm interested in picking up a used Heathkit SB-610 in order to monitor my
sideband wave forms.  From what I understand, all I'd need to do is connect
the antenna out of the K3 to the SB-610, and the antenna input to the
SB-610.

Can anyone with experience with this scope know if it will work well with
the K3?  I think this SB-610 has a 455KHz coil installed as well.  I do
believe they can be switched out for a 4-6KHz  coil for monitoring a
receiver's final IF.  I don't recall what the final IF of the K3 is
operating at.

James I am not sure you will get value for money from an SB-610, they
date from the days when a decent oscilloscope was big and expensive.
These days 'scopes with the capabilities to monitor your peaks are
general purpose test items and don't cost much. The K3 also has a two
tone test oscillator built in. The IF output of the K3 is quite low
level and is centred on 8.215 MHz, not the final IF of 15 KHz.

For my money, I would look for a general purpose oscilloscope for the
shack and an SDR receiver ranging from the low cost Softrock IF, to
LP-PAN or the more expensive general coverage ones. These will give you
a panoramic view of the band and be far more useful than an SB-610, even
if it could be converted to work at the K3 IF output.

The SB610 is a transmit monitor scope. It is not a bandscope. The model
SB620 was a bandscope.

The SB610 is still very useful for monitoring your transmit signal through
an amplifier for proper modulation and trapezoidal waveforms etc. Good
luck finding parts.

The SB-610 was basically a transmit monitor scope but could
also be used to monitor receiver IF's up to 6KC (at least
according to the manual) but I have never used one that way.
In any case the IF on the K3 is to high.

Thank you all for your replies.  I will only be using the 610 to monitor my
transmit waveform in sideband and AM.  I just wasn't sure how the 610 could
be used to monitor receive IF.  At this point, I don't think I'll bother
with that function for now.  Anyway, I was able to get a restored SB-610
from eBay for a fair price.  As for a spectrum scope, I'm still waiting to
see if Elecraft will release a stand alone unit.

Hi Bob,

I've found a nice SB-620.  Do you know if it will work with the K3 and it's IF out as a spectrum analyzer?

Nevermind... I'll have to re-wind the IF coil on the SB-620 in order to match the IF on the K3.  It may just be easier to find a used LP-PAN instead.
