books / resources to learn about servicing radio gear?
I am interested in working on my own radio gear, doing some repairs, diagnosing and swapping out problem parts/boards, alignment, buying several broke radios on ebay and making 1 working radio, stuff like this. maybe when I learn something helping the local repeater clubs work on stuff.
I have been an ham since jr high, did biomed engineering as an undergrad, so have taken 200 level college courses on circuit theory and design, digital logic, etc. am comfortable with albeit kind of rusty with soldering/desoldering. Have clipped diodes and replaced fuses, simple type stuff on ham gear. Pretty comfortable with various moto/icom/kenwood programming software, so I am not a complete idiot starting with nothing, and I understand some of the gear I might want to do this stuff gets kinda spendy. I also understand I will probably brick a few radios on my learning journey. Mostly interested in doing this just for doing it.
So, all that said, what resources would are recommended? Mostly looking at books and learning materials to start, but of course also gear as well.
Books?
Websites? (I've searched around, found a few so far.)
Manuals?
YouTube Channels?
Other resources?
Gear wise, have basic soldering stuff, basic fluke meter, cheapshit SWR meter, cheapshit freq counter, good set small screwdrivers, some patch cables. What else?
As far as monitors, IFR 1200 has been recommended, any other monitors that are good to look at? I see pretty huge variations in price. I may be able to get access to one through local ham club and hold off on big investment for the time being.
Thanks for any helpful recommendations you can share.

Re: books / resources to learn about servicing radio gear?
I see there is a lot of discussion about "what is the best service monitor" on the board.
Re: books / resources to learn about servicing radio gear?
Usually the best way to learn is by doing and making mistakes along the way.
The service manuals often have pretty detailed theory of operation and trouble shooting guides for the specific piece of equipment. This information can often be leveraged across a number of manufacturers an models
Spent a huge amount of time reading those and looking at the schematics to understand what was going on inside the hardware. ( there is a reason why they make the manuals )
Often time the service manual is not available to does not go deep enough and in that case the data sheet on the core components can offer enough information to work a problem as well.
If you are on the bench discreet pieces of test equipment are far better in most cases than a single service monitor ever will be .
The service monitors for the most part are intended to provide a field solution or a very targeted test process at best.
The quality of the service monitor varies with manufacturer but ease of use and long term support are also major considerations.
The later IFR 1200 is very easy to use in the field and the major unique part would be the CRT's which seem to have a very long life . The actual measuring capability is decent and usually good enough for repairs but final alignments for current radios I would do on something more accurate.

Tuning & alignment procedures for Motorola radios will be found in either CPS help files or service manuals, depending on the model.

Oh boy. Generally, it's plug yer nose, and jump into the deep end of the pool.
You know, back in the olden days, there were actual classes on basic electronics, but you had to get hands on time to learn how to troubleshoot and repair. It takes a while to learn how to solder well. But, everything had a service manual with a detailed theory of operation, and people were willing to spend the money to repair and maintain things. You read the manual, and dug in. If you were lucky, you had a working one to compare voltages and signal levels. After a while, it just soaked in how to do it, and when new stuff came along, it was that much easier to figure out.
Nowadays, everything is low cost modular design. You replace a black box. Generally the one with the red alarm light on it. You may or may not have to understand how it all knits together. Sometimes hammering on a keyboard fixes stuff. Kind of like the old days of banging the case, but now you do it in software. Wires and power still seem to the be the most common problem. And there is a whole lot less soldering. But, if you do solder, generally its with a hair dryer now.

Two books by Harold Kinley:
"Standard Radio Communications Manual with Instrumentation and Testing Techniques"
"The Radioman's Manual of RF Devices - Principles and Practices"

Re: books / resources to learn about servicing radio gear?
I ordered both the Kinley books. Thanks much!. Looks like exactly what I was looking for.
I have a few service & theory manuals, I will keep the radar up for more.

Re: books / resources to learn about servicing radio gear?
Kinley used to have a monthly technical column in the old Mobile Radio Technology magazine.
He teaches at the practitioner level rather than at some esoteric theoretical level.
His books will give you good guidance.

Re: books / resources to learn about servicing radio gear?
Definitely thanx for the book titles. We are trying to figure out how to train new techs so some of us can retire.
Re: books / resources to learn about servicing radio gear?
Those columns were great. I would love be able to purchase a full collection of them. It would be a great resource.xmo wrote:Kinley used to have a monthly technical column in the old Mobile Radio Technology magazine.

Re: books / resources to learn about servicing radio gear?
I really miss the old Mobile Radio Technology magazines, I still have most of my back issues. Kinley's articles were very informative.xmo wrote:Kinley used to have a monthly technical column in the old Mobile Radio Technology magazine.

Re: books / resources to learn about servicing radio gear?
I just ordered and receive this manual. Although it's a bit dated as it related to the type of test equipment used, it's still very relevant. It goes through step-by-step testing procedures of AM, FM and SSB radios. Good theory and detailed explanations of the testing procedures.xmo wrote:Two books by Harold Kinley:

I would highly recommend this book for the beginner, or seasoned radios tech.
Re: books / resources to learn about servicing radio gear?
Harold just had quadruple bypass surgery so if you're trying to buy his book direct from the author on Amazon you'll have to wait a bit.

Re: books / resources to learn about servicing radio gear?
ordered a used copy of that one also, looks intriguing.
Re: books / resources to learn about servicing radio gear?
"Land mobile Radio Systems" by Edward Singer was a good book too. It might be a little dated now but still is a useful reference once in a while.
Re: books / resources to learn about servicing radio gear?
The R2200 Service manual is a good read as well, describes the functionality of the features of the service monitor and at the end of the manual it has information on how to connect equipment to the service monitor.
