Another great tutorial Peter. Your combination of great equipment and meticulous skills are an inspiration to us all. I'm glad you didn't have to replace C1310 hiding in the corner between the two relays. It is amazing how lively dead SMT components become when they are removed from the board. If they manage to escape my bench they are lost in the carpet forever. Looking forward to the next video 73's
To sound out the word continuity, it sounds like: Con tin ooo it eee Thanks for taking the time to share your knowledge with us. I learn so much from watching you work!
Thanks Peter for the great video and the many others you have made. It gives me more confidence in diving into the more modern radios. I came out of the old steam engine days and bigger is better ha ha.
+DALE BROOKS Hi Dale, I'm glad that you like my videos. Well steam engines are pretty nice machines so no problem what so ever... Thanks for watching my videos. 73
It's very interesting that the traces to the diode are quite large. Almost as though they expect an amp or more could be flowing on this trace but the diode package doesn't seem to match it based on it's size. It would be interesting to know the diode's part number and specs.
+John Borchers Hi John, it is not power what needs to be considered while developing a rx circuit but attenuation and return loss. As higher the frequency as more this factors needs to be carefully planned on a 50Ohm transmission line. The diode is a PIN diode 1SV271. Thanks for comment!
Nice repair, Peter. When checking tiny SMD's, I use a small tin with a thin layer of spongy rubbery foam in the bottom of it. It helps keep the component from jumping around. And if it does jump, the tin helps keep me from losing it.
+TRXBench No problem, Peter. Also, Peak Atlas has a nice little SOT-23 tester adapter available now. Here is the UK website: www.peakelec.co.uk/acatalog/pca23-sot23-test-adapter.html
Very enjoyable Peter! Those silly little one way thingy's :^) That radio brings back memories. Have you put up any Christmas lights yet? It's just about that time here.
TRX Bench You might want to beg, borrow or steal one of Paul's custom output boards for that rig. It sure cleans up things nicely! The relays are much improved in his version!
Thanks for the quick answere. I did not know that about the diode test function. Old school I guess, and by tweezers I mean the ones you use with a DMM to check resistance. Keep up the great work. And very good english. Thank you again, Greg
Thanks for the video! Very helpful. Laughed at the jumping diod, hi! May use an useless SMD-board with cut paths as an adapter.Just solder the suspected smd component and check. Or double sided scotch tape as other people say. Thanks again!
Well done. It would be helpful if, as you follow the signal path, you tell us about the function of the suspect part. For example, some viewers may not know how a PIN diode works or what it does. So showing that applying a bias voltage turns it on and allows the signal to pass would be nice. I enjoy repairing broken radios and learn a lot from your videos. Thank you!
+k1mgy Hi Mark, yes I fully agree that is the reason why I also do tutorials. If I would put all in one video it gets easily overloaded. In an earlier tutorial "The TX Audio Path" I already explained how a diode works in a signal path and why we need to bias it. So there is the PIN function to still talk about. Thanks for comment!
Adjusting alignments can be a pain, is it very common that they ask for that we small board to have the alignment to be adjusted would it be a common problem that this little master board would go out of Spec peter, so much learning from an expert something you wouldn't get from a text book as one would say the tricks of the trade little diodes can be a pain to change so awkward where they are positioned Peter well done another success :)
Hi Peter.. Great video again my friend and good fix too. I can offer a little help with your jumping components. Get a bit of Blu-Tack OR better still, some double sided adhesive tape, and stick the component on to it whilst you test it. That should stop them trying to escape :) Cheers John
+orbiter8 (John) Hi John, thanks for watching my videos. Yes you are right I know this little trick. But as always you think you can handle it just for the vid. But in this case it was a kind of entertaining hihi. Take care may friend.
+TRXBench Understood Peter.. I did laugh when the diode shot across the table. Although finding the things again afterwards is sometimes not so funny :)
I get the impression from the number of repairs done to this Mark V, that it is not a dependable rig. Is this the case or are there several Mark Vs being repaired? I enjoy the slow paced method that you use to describe your thought process as you work. You have helped me understand the troubleshooting process and the importance of block diagrams and flow sheets to isolate the problems. Thank you for these fine videos!
Hello Peter! My XYL will hear you speak when I am watching your videos, and she says, Where is he from?" Lol! I tell her I would love to speak German as well as you do English! Keep up the great videos! Thanks!
Nice job Peter. I'll echo the recommendation by orbiter8 to consider using some tape or Blu-Tack; if you don't have any double sided tape just use single sided and tape the component down onto a piece of white paper then with very sharp probes simply pierce the tape thru to the component leads. Yeah, you might have to worry about conductivity of the tape I suppose but for simple components like this diode it shouldn't be a problem. 73 - Dino KL0S
Wow Peter, you nailed that diode fast. Nice job! I thought it was pretty hilarious when that SMD diode would jump all over the place when you tried to probe it. I had noticed a Rigol DS1000Z series oscilloscope on your bench. I just picked up one myself. I think it would be great if you could demonstrate yours. If not, at least tell us your opinion of it. I did a lot of research before buying mine. I mean, a four channel DSO scope for only $400US? Are you kidding me? Yes, a "no-braIner." I was using a Tek 465 analog scope previous. Nice work 73s Tom
+AntiqueRadioandTV Hi Tom, yes it was more then hilarious. Nice sequence when I saw it afterwards while editing the video :-) Yes the rigol scope it a decent soled piece of shop equipment. I would not call it development tool but it is more than worth the money. This scope has a wide range of capabilities and with four channels it is a kind of logic analyser as well. Especially for ham radio controller circuits. 4 channels are very often fitting the needs with clock line, data, read, write and what have we... Unfortunately the schedule is not allowing to do a video on the scope but I have some videos up where I use it. For example the PEP vid.... Thanks for comment! 73s
I'm glad too see that I'm alone in which SMD components jump like crickets on the workbench :) ahahahaha. Great video, nice to learn with you, thanks Peter. 73s de IW0HEX Pasquale.
+Gregory West Hi Gregory, the SMD tweezers managed this job and I'm really glad to have them. No I didn't test the diode only in one direction but the DMM was set to automatic diode test so you don't need to reverse leads. Thanks for feed-back!
Good morning, Mr. Carlson. I have the RX2 of the Yaesu FT1000 MARK-V Field working perfectly, but the main RX has a signal deficiency and, when the signal is strong, it presents distortion. Where do you guide me to check? Thanks. Maurício.
Hi Peter, I've just watch your video, because I have the same symptom on my Mark V...Do you have a reference for this diode ? SU271 or maybe a BAR64-03w can work ? It seems that this fault comes very often on this transceiver.
I have a Mk V that has low receive. The sub receiver hears better than the main receiver. Also when I transmit into a dummy load. I show full output and full SWR. Any ideas where to start looking? The attenuators are working as well. I am good on QRZ. TNX Chuck WD8BXS
Thanks for another great video Peter. Looks like you got lucky on that repair.I seen a lot of messed up radios from folks not knowing how to do it correctly.Check out my latest video on caps and techs gone wild lol.Thanks for another great repair my friend
I have a FT-1000MP and I really like it, it is full featured. Now I now what to do if one of my friends pulls up in my driveway running a KW! (That would be rude, right?) Thanks,,,
Hi, sorry can't help you with a repair shop around NY..I'm in Europe..But contact Buddy from The Radio SHOP her on YT. Search for his channal and ask him, he can help..73
Just a comment on holding most smd components when they are removed. A locking tweezer with plastic tips or preferably ...softer even, with heatshrink on the tips are great. A mini pana vise with attachable rubber jaws, are also great. Again, just a suggestion. Smd's are a pain and patience is so very important! '73

+hussain alonzi Thanks you Hussain!
To check SMD's, use one of those "sticky" traps intended for catching bugs or mice; they won't jump away from you if they're stuck down.
