I built one of these back in the day. Great fun......

Hi Bruce, thanks for your video. Could you kindly let me know how you carried out the port extension for this exercise? Were both the adapter and pcb attached to the VNA when setting electrical delay? Many thanks in advance for your reply.

I owned the Panasonic back in the 90s and remember one drawback that it had. If I remember right the IF is 2MHz and on shortvawe it would pull in the image station from the band beside the wanted band. Weaker but still very anoying. Very sensitive though. Thanks for the comparison. Three very good radios and a lovely place you have there.

Awesome 👍👍👍👍👍👍

Honestly i have lits if vibtage boombox but when iy comes yo reception panasonic is the best reception of all

Very high quality, multi featured, beautiful radios of the golden era of the 70's! Thank you for this video!

I used to have the Superadio 3. Best portable DX radio from the 1990's on AM. Now I have a CCRadio 2e which has the best AM signal to noise ratio I have heard so far. The difference is that you have to turn the volume up on a weak signal, whereas you didn't on the SR 3.

There are two other methods of measuring impedance. The method shown in this video is most accurate around the 50 ohm point (S11). Putting the component in series between Port 0 and Port 1 is used for higher values of impedance, and the shunt, whereby the Port 0 and Port 1 are connected straight thru, and the component is connected from that straight thru to ground. Mostly used for less then 50 ohms... W0QE has an excellent video on this very subject. "Three methods to measure impedance with the NanoVNA".. Thanks for the video

Very interesting test. Thanks!

In my opinion, am and fm are nearly dead, i might see almost all stations disappear in my lifetime. But I still have a strong desire to have stuff that works. It irks me that it seems car audio antennas aren't the best but there's not a lot of expertise when it comes to anything aftermarket that might be an improvement.

You fail to acknowledge the tone controls are very important for reception the SR2. Bass helps greatly in bringing stations out of the static and reduction of the same helps eliminate sideband splatter. The difference between the SR2 and Panasonic is next to nil.

I liked this video Bruce! I have a large collection of transistor radios and I have to say that except for its b.f.o., my rf2200 is my best. Can't beat its tone quality either!!

0:12 Don't worry only an corner is missing.

Westinghouse SevenSea Multiband: any comments? I found one in thrift store for cheap - no replacement for my uncle's Zenith which I loved when a child back in the 50's

nice job 👍

73 from Rio Claro SP. Brazil!!!! Thank you!!!

Every radio stay on different angle to transmitting radio station. How it possible to compare them this way?

Hi Bruce, thanks for that. It was very helpful. Please can I ask where you got that SMA component tester PCB.

The superb Performance of the Panasonic RF 2200. It was indeed the first of it’s kind. And in most cases as in mine, the Panasonic is very robust and built like a tank. Love this radio on shortwave!

Hello Bruce. As an experiment try placing your receiving coils flat on the ground. This would be similar to what hams & swl's are doing with their "Loop On Ground, (LOG) antenna. Possibly the log antenna may be useful for the am broadcast band.

Good comparison! It is amazing and thrilling test! Ive long thought the RF2200 is the strongest as far as the sensitivity goes, but I need to update my thoughts now. That great and only a huge GE? who has exited from home electronics earlier in 80s ? The Superadio is super. But after all, I love the Transoceanic, tube is better. I have not mine though.

Why can't a trimmer capacitor be replaced?

I’ve never had the chance to try any of these radios, but if it comes to the ‘good looks’ department, I think the Transoceanic wins hands down.

All 3 are fantastic radios. What I noticed is that most great radios are geared for or stress one or two bands and the other bands are well, good but not exactly Mt. Rushmore. Sony’s best transistor radio included in the video and there you indeed DO have the Mt. Rushmore of transistor radios between swap meet price and NOS price. I myself enjoy an AMPLIFIED DX experience with the treble and bass set perfectly. So I have two Superadio IIs. One I’ll use regularly and the other one I’ll just check on from time to time because it’s NOS in the box. If someone has one for sale the best advice I would give is after demonstrations find out if it were made in Malaysia 🇲🇾. Those are the only ones you should consider.

tha great rf-2200 dr-22 Truly one of the greatest radios in this category

Great video Bruce. Hard to beat the RF-2200...I love mine.

I would like to see you demonstrate that loop on the styrofoam box. I can imagine its pretty good.

Not bad!

I need to measure +30dbm. Do you recommend any other model with this price range?

Hi, do you know if this model have a selectable manual or automatic attenuation? I need to measure +30dbm

What is your QTH?

Nice video, Bruce!

great job. i bet the superadios would shine at night. surprised by the poor performance of the ccrane....

I still have some of these radios-interesting test! E

Excellent work, Bruce. Looks like a lot of effort and very much appreciated.

Thanks, Mr. Carter, very interesting!
