- Here is a short demonstration and overview of the Kenwood SM-220 Station Monitor - a multifunction accessory for the ham / amateur radio shack.
As mentioned in this video, here are links to the other videos I mentioned:

Great overview of a classic piece of gear. Surprising how many people don't know what a station monitor is. I get questions a couple times a year from people asking me to describe their purpose. Good job.
SM-220 has been in my lineup for many years, great sort of "all in one" box!
Always enjoy your videos; this one no exception. Well done!
Nice, always worth the time watching and learning from your vids. Happy New Year!
Nice review of a classic piece of test gear. Thumbs up
Another great informative video, thanks!
RTTY is very often used for ham radio contests. The next big contest using RTTY would be the ARRL RTTY Roundup on January 7-8, 2017. 30 hours. If you are a ham it is a great opportunity to have some fun and if you aren't (yet!) you can still listen in and run the decoding software to see some of the activity.
Thanks so much for this vid. I just keep mine between the rigs and the amp and keep an eye of things.
Great demo. I have one and never run the station's HF amp without it on.

Just got one and am learning how to use it with my FT-101zd
Cool. I just bought a TS820S that came with one of these monitors, the remote VFO unit, MC50 desk mic, and the filtered speaker. The guy also had a mint SB221 but sadly it was sold just days before I called.
I know this is an old video, but thank you. I just received a TS-820S setup that included one of these and I'm not trying to figure out how all of the pieces and parts go together.
I just ordered one of these to go with my new (to me) ts-820s setup. I am a new ham with an IC-7300, but I wanted an older rig I would work on, restore, and play with. Why not something from my childhood years!?! Ok I was a kid in 1978, but still I love the nostalgic feeling on running this old rig. Honestly, I don't find a huge difference between the Ts-820s and the 7300 in terms of real world functionality. Sure the waterfall is nice, and the variable passband is a little nicer, but it's not like I have encountered many signals where the 7300 is leaps and bounds better. Typically they are about the same.
Nice piece of gear.
Great! I was thinking of getting one of these for my beautiful condition TS-530S - but alas, I'm going to save my money for an IC-7300. Sad!
Nice! I had no idea the station monitor had an IF spectrum analyzer.
It does, but ONLY if it has the *optional* adapter installed. And of course, there are only two variations available - the BS-5 works with 3.395MHz IF signals, and the BS-8 works with 8.83MHz IF signals.
I bought one hoping it had the panadapter but no such luck, I had to build two panadapters, and am on to number 3, or should I say one panadapter that will work with various IF stages for multiple transceivers. I made the 8.8307 MHz for the 800, and then did two more Xtals and two more IF transformers, so I can do the panadapter with a TS440, TS450, a Yeasu and some other stuff. The screen is so small, I took an old student grade Tektronix O Scope with a dead 2nd channel and made that a station monitor with a large(r) CRT screen. These SM220s are beautiful inside. Kenwood laid these out so neatly, and they really are just gorgeous inside. 73 KI7AQJ
I am interested in doing the same thing with my yaesu FT-736R and FT-767. Could you tell me how you went about building the pan adapter?
What I would love see is your take on Mr Carlson Lab's super probe.
I'll have to take a look at that.
Nice video, as usual. Although, that trace needs a tiny little bit of rotation, no?
73 and HNY de CT7AFR, Emmanuel.
Yes, a little bit. On the SM-220, this is done by loosening a pair of wing-nuts on the rear panel and rotating the CRT. Slightly different magnetic environment since I moved the shack resulted in the tilted trace, and I haven't gone back to adjust it yet.
Thanks for showing i'm thinking of getting one of these and the BS-8 for my Ts-440Sat But have to figure out how tho bring the 8.83 IF out to a BNC on the back of the tranciever The 430 and 440 never were intended to use a station monitor unfortunetly.73'jim KB1PFL
Well Iguess I lucked out at the Whitman ATC Winterfest today i saw one for 125 dollars with a TS430 that had the Mod done for the scope the gentalman at the table in front of me had one of these and he bought the radio and I bought the monitor For $50.00 dollars we plugged it in and he said all the functions were working correctly I took the top off and the BS-8 Pandapter is there all it needed was a Reticle screen and bezel which I just purchased for 20 dollars ob ebay Boy was I lucky.Jim Kb1PFL
Reminds me the IFR 1200/1500 test instruments family
Thanks for the video.I bought one of these about a year ago got it for a song about 15 dollars at the flea!
It has the BS-8 ,and i had seen an old QST article a few years back about bringing out the iF in the TS-440sat to use one of these, and that is the mod i'm about to do. i see in the manual they talk about using two different iFs at the same time one 1st iF going in the back and the second iF going in the front V.input i see you are using only the rear input 1st iF for band monitoring, so i will be able to see band activity.... what does using both iFs at the same time Give me over only using just one? it isn't mentioned in the manual or am i just reading it wrong?73'Jim KB1PFL
The first IF output is a wideband output to be used with the pan adapter (bandscope) to look at activity over a large portion of the band. The 2nd IF output which is brought to the front of the scope, is a narrowband IF signal - the same signal that goes to the demodulator for reception. So, it let's you see the RF envelope of the received signal (in OSC mode) similar to the view you see in MONI mode for your transmit signal.
hi which radio do you find yourself using more? the ts830s or the ts870s ? thanks
I definitely use the TS870S more than the TS-830S. But, these days, I spend a lot more time on QRP CW using a Penntek TR-45L.
Sir W2 i cant remember correctly, but did you make a video of an amplifier that had constant amplitude output? today we had discussion at college, and i have foggy memory of something, but i cant find any info about that.
I made a video on an audio leveler circuit.
Thank you... i was looking for that video.. Cheers !
What model are the 2 rigs there? I can't decide if I want a TS-830S w/6146's or go all solid state with the TS-930S. I like the new technology in the 930, but those late night glowing tubes keep calling me back.... de AA9GG
The one on the bottom is the TS-830S and the one above it is the TS-870S.
Hi, how do you set up the sm220 with the 830S? I know the 830s has two IF outputs let me know what I can do thanks!
For the TS-830S, you would need the BS-8 Pan Adapter installed in the SM-220 in order to do the spectrum scope. This connects to the IF 1 output on the back of the rig. If you want to monitor the received signal envelope, then connect the IF 2 output to the front panel V INPUT and run in OSC mode. To monitor the transmitted signal, connect the TS-830S RF output to the RF INPUT on the SM-220, and the RF OUTPUT on the -220 to the antenna system.
w2aew so i need a BNC to RCA connection on the back of the 830S? What are the cables called that I may need to buy?
Thanks!
@@danielpenaofficial4186 The pan-adapter connection is simply and RCA to RCA cable. The 2nd IF connection to the front panel of the can be done with another RCA-RCA cable and an RCA to BNC adapter. However, in my experience, the use of the 2nd IF with the SM-220 is of very limited value - I've never used mine this way except to see how it works.
What was the reason for doubling the IF with the newer models?
The TS-830S is a dual conversion receiver, with filters in both IFs, while the TS-530S is a single conversion. Thus, better filtering in crowded conditions, and the ability to add variable bandpass tuning vs. simple IF shift. Here's an excellent link describing the differences/changes between the Kenwood hybrid rigs:

Ah. Thanks for the reply and link, Alan.
Will a SM-220 connect to my TS-520s Station...?
Yes. For Transmitter monitoring, it works with all HF radios. For the bandscope with the TS-820, you'll have to have the BS-5 Pan Adapter installed in the SM-220. The TS-520 doesn't have a connector for the IF output to connect to the pan adapter, but the SM-220 manual includes instructions on how to add this modification to your TS-520.
Great videos,can you please help me I want to connect my 17 inch lcd tv to a old 3 inch scope I don't think it's as easy as plug n play .thanks
Definitely not plug and play. There's no simple way to do it. If the TV has an analog video output (NTSC) then you might be able to use the circuit in this video, but you will need a scope that has a Z-axis input.

w2aew .I was hoping to view my scope on a bigger monitor but I guess I will have to strain or put it on shelf .many thanks
It has composite ,svga and vhf
Maybe use a small video camera (GoPro, webcam, etc) and connect its output to TV or computer.
I'm going old school I got a magnifier lamp on the adjustable arm. makes a big difference
I understand 1 kHz but why there is 1575 Hz?
For two-tone testing, the tones need to be non-harmonically related. So, this is simply a choice that meets this criteria as well as being close to the center of the audio bandpass of a typically ham radio transceiver.
i have one of thes what can i do with it
The video describes several things you can do with this unit.
@@w2aew i only have the unit
@@jacoblush By itself, it is really only a very basic, limited function oscilloscope. But, given that it has a higher value to ham radio operators, you might think about selling it (typically $100-150) and using that money to by a more proper oscilloscope.
@@w2aew i got it for free thank you
