I thought I knew quite a lot about working on vintage radios until I found this channel !!! Huge respect sir . Regards from the UK .

So early my capacitors are still reforming under the dulcet tones of Mr. Carlson .

Mr Carlsons lab you are good at restoring vintage shortwave receivers and alignment of vintage shortwave receivers 🎉🎉🎉😊🎉

All of your videos are interesting Paul, but I think this is my favorite to date. All along the alignment I couldn't help wishing I could see how the alignment was done at the factory. Wouldn't that be fascinating! To see the gear they used and what sort of technicians did the procedure. Probably young ladies trained to do the work. I can dream... Thank you, Paul. Don't go away. I'd really miss your videos. 73, from Paul (me) K8IDX.

That locknut wrench is pretty you have one! Fantastic what can be done with the proper gear. Thank you, Paul!

Thank you Mr Carlson, we greatly appreciate your expertise. Your Video will help me when I go to sweep align a 1938 112 Trav-ler radio with a Broad - Narrow band pass switch. This I.F. alignment procedure of the RCA AR/CR-88 radios reminds me of the days when I did sweep alignment of TV I.F. and color I.F. back in the day when I did TV repair work. Getting the coils adjusted just right was tedious indeed and having patience.

Many years ago in the U.S. Navy Sub electronics school, our instructor "CPO Ward" asked if anyone in the class had "Spectrophobia", no one even knew what that was, He went on to say it was fear of Ghosts, then he brought out the Spectrum Analyzer and proceeded to show us the alignment graphs and how they resembled the shape of Ghosts in a white sheet. LOl, I still chuckle at that!

Paul, it's a credit to the original designers, manufacturers and your restoration knowledge and skill that this radio seems so stable and, I'm sure, will match the performance of many current solid state units. I'm only sorry that I sold my AR88 back in 1973 😒

[hestheMaster]

It probably never had an alignment this correctly since it left RCA. Great video Paul.

I don't have an AR-88, but I do have an R-390a can't wait to see how bad I screwed it up according to Mr Carlson. I will definitely be redoing the rebuild on the R-390a after his video restoration. Thank you Paul for all you do.

To a layman like myself, this is very akin to the technical jargon overload video. However Mr.Carlson's lab is quite pleasant to fall asleep to :)

I've really enjoyed this series. A lot to learn about these old receivers. The lab looks great! I really enjoy the layout of equipment on the bench. Looks like a busy city of sky scrapers of test equipment. Both eye pleasing and ergonomically convenient.

Mr Carlsons lab your utube videos are awesome 👌 👏 👍 😊

[navelriver]

I know little of this but thanks for keeping this technology alive!

[theladyjaiproject]

I would liked to have seen the IF response curves before you started. Would have been interesting to see how close or far off they were before you began. its just my way of seeing the improvements made. I've aligned many microwave band pass filters and yes it can be very tedious. Great series. Makes me want to go find one of these to play with.

Mr C, you can move that camera as much as you want. Your ability to get your point across is greatly aided in the shots of the scope vs the control points you are adjusting! As always, informative, and interesting to watch! Keep it rockin, 73 de Pat KK6PD

Grazie Mr Carlson per questa stupenda lezione di radiotecnica !

[mikefinn]

Paul very thankful to you for taking the time showing this alignment very helpful to the rest of Hams I will use your techniques on my Hammarlund receiver. Great to enjoy coffee and watch the
best channel on You tube. Great Job Paul 73s

Thank you for the great demonstration of sweep aligning a receiver. I have used sweep aligning for years on the commercial equipment that I serviced. Someone asked what the sweep rate was. I used to use 20Hz. This is a declining art as receivers are now all on one IC. This type of alignment is also critical on receivers handling video and data as proper bandwidth is necessary as much as amplitude.
Again, great job and I appreciate your attention to detail.

I stand by my previous statement.
