content: This guy is out there claiming to be a super best Stryker radio tech but I don't see anything special, Wonder if he is really worth sending a radio toSomething does not look right about 19:50 in on the am waveformhttps://youtu.be/kWGyISbNfHM

content: Yea, didn't watch the whole thing (Just skipped around), but he sounds like a bit of an idiot. Especially at the end where he babbles about reflected power... I'm hoping he was doing his tests into a dummy load and not over the air!

content: American CB radio "techs".I believe in "trust but verify" but at the start all of the meters to measure the same thing..... no trust in the gear? needs 5 meters?And why does reflected power of a dummy load (I hope) have anything to do with the radio?That doesn't compute, just like the bank of meters... it seems more for show.But there is emphasis on reflected power. What is the DUT? Is it the radio, antenna/dummy load, or feedline?Most of the video is look at this meter look at that meter.....Let's talk about mass production but... not actually know how its done, because robot arms don't solder every joint.....Cant believe that unskilled labourers can solder badly. Ok.There are some just absolutely crazy moments. Like the speaker impedance thing and needing ferrite because of impedance. WUT?At the end, the am envelope looked very bizaare, and seemed to barely break 50-60% modulation. clearly a misadjustment and/or circuit fault.I want to see the guy that was transmitting from 24-30 Mhz at the same time. That's got to be an impressive feat of misadjustment and/or synthesiser hackery.In the end it was 95% theatrics. Serious hints at narcissism. All the "we" - Mouse in the pocket, etc.I am still trying to get my head wrapped around the emphasis on reflected power having anything to do with the DUT - which is clearly the radio.Talked about spectrum and made a pretty out there claim but clearly doesn't have an SA so it's just conjecture.He needs to check his feedlines, those meters, and his dummy load. There is an issue. It's probably all the bloody meters in line.Not missing anything here. Nothing to see.... move along.....

content: We repair CB radios.Just some thoughts on repair and adjustments of these radios:Our favorite comment to people who wish to change the radios internal functions (Mods) is:"Do you really think you know more about this radio than the engineers who designed it?"This guy thinks he does.I have no idea what he is talking about most of the time.Sometimes I think his scope is flat topping because the signal is higher than the scale. The represented signal cannot go beyond the screen.I cannot see that any of his measurements would indicate splattering, if it was present.More "thoughts":In generalwe try to keep the carrier on AM about 1/10th of total output power. This works most of the time for good sound and does not abuse the finals.The antenna system is a big cause of poor performance and damaged radios. Not surprising in that the antennas get bumped around frequently.If you are concerned about a Stryker Radio:Stryker radios are difficult to service since Stryker does not release service information including schematics. Only their approved technicians have access to information and parts.Although there is nothing wrong with Stryker radios, we do not recommend them because of the service problem,

content: The gain was so high on that one radio that the "DC transformers" were humming. How much crap does he have inline on the output? One meter measures reflected power, and the two others forward? why 2? His MFJ analyzer gives him forward and reflected power, plus frequency. He could use just. I know MFJ doesn't have a stellar reputation, but it looked accurate enough for CB work. I kept thinking that one 'accident' could wipe out all of his test gear since all of it is always connected.What is the CB Service Master breakout box? I have worked on a lot of radios and never aligned anything injecting audio through a speaker into the mic. Sure, a quick whistle to see if there is a response, but how do you know what the input level is? I saw BK Precision on the Service Master box.I wonder where that red "reflected" meter is in the output chain. It looks like it may be the last thing before the ant/dummy load. It might show something different if it were the first thing closest to the radio. I looked through some vids on his YT page to see if he did any bench tour stuff, but didn't find any. He did do a couple of videos on "restoring" those thruline wattmeters. His restoration consisted of painting them and rubbing coconut oil on the leather strap. He proclaimed himself a "bad MF whiteboy" after the red paint job resto.The guy is a character and kind of funny to listen to. He reminds me of the drunk guy at a bar that is telling you how something that you are an expert in works...and is all wrong. I like the hand gestures in front of the camera with the tattooed fingers. Index finger with an "E". After sampling a few vids, I believe one hand says "love" and the other "hate", that's clever and original.Must be a CB thing. I saw another youtube guy working on those type radios with similar "attitude".

content: I think we have been there before with this bloke!His mental processes are seriously strange, & he seems to spend most of his time pumping up his own ego & reiterating how "knowledgeable" he is.It gave me a headache, & I didn't watch the lot.I think we could coin a new acronym------- TMBSDNW!Contrast this crap with Alan W2AEW's YouTube videos:-Alan sounds like a friend showing you something in his Ham shack, & treats you as an equal---no ego, just a desire to pass hisrealknowledge on.

content: So I can’t sleep and thought I would look up the other CB adjuster guy on Youtube that reminded me of this guy. Apparently this guy ( Fine Tune CB Shop) is aware of our friend Black Ops 204 and has a video critiquing his radio tuning expertise. These guys might be brothers. Their videos are very similar. Lots of self indulgence and telling you how great he is. Anyway, I got a chuckle out of the CB/ Youtube war that may be brewing over who has the most thruline meters in use.https://youtu.be/blwKopcBGr8

content: I deal with a lot of CBers. They are in love with Thruline Meters. If you have one to sell find a CBer, he will pay top dollar. I do not know why, since they are concerned about "Peak" output most of the time.They never are concerned about their spectrum output. Good thing we do not have to worry about TV interference anymore, lots of these radios are tuned with a huge 54 MHz spur HA!!Sometimes you can hear these guys on two or more adjacent channels also.

content: There are some excellent CB users but they tend to be the quiet ones.Sadly the loudest ones tend to be complete idiots and they tend to be the ones either making money spreading such utter garbage or handing their money to the ones spreading it.The muppets who inhabit 'Superbowl' can often be heard in the UK on three or four channels either side of 6 such is the 'quality' of their radio tuning expertise.The fascination with 60 year old RF meters is weird but I *think* some of it comes from a basic misunderstanding.I've been told by one 'tech' that he doesn't need a spectrum analsyer because his Bird meter only has a 30MHz slug so none of the measured power could be harmonics as it wouldn't measure it.I reckon another bit of it comes from military service, there seems to be a belief that anything bought by the military must be the absolute best in class and there have been a *lot* of Bird meters bought by various countries.

content: Bird thruline meters are high quality brick Outhouse meters. They’re easy to twist the slug around to measure reflected power. You can drop it down 4 flights of stairs and it may barely get a scratch. They are nice meters and come in several models. You can get an element with a coupled sample port on it too. The problem is you need a relatively expensive element for various power levels and frequency ranges. I like the meters, but agree that CB guys have a weird fascination with them.

content: All true, but that doesn't mean they're the best piece of test gear for the job, they're adequate and accurate enough for most uses.There's better out there now (Including other Bird products.)
