+Mr Carlson's Lab Great repair video Peter! Wow, at 32:54 looks like some bad arcing or something happened in that radio's past. A few heated inductors as well in the filter section. That radio is very happy that it came to visit Peter!
+Mr Carlson's Lab Hi Paul, yes as I said a couple of 100watts. I should have shown the hole in the pcb. It was really a heavy impact. What you can still see are carbon black on the pcb and on some components. The coils are fine have tested all. Thanks for watching how many coffees did you need hi hi. 73 Take care
Another great repair Peter. Really nice troubleshooting skills and explanation of the problem. The 1000M is a very nice unit and I have worked on a few here.Thanks for sharing my friend.
Another nice repair job. Somebody was already in but didn't understood the circuitry. Glad you did hi. Well done Peter. Another radio saved. I am surprised that so little damage was done with a couple of 100 watts input at rx. In the old days we used a neon light (lamp) in the rx path. Peter 73 untill next time
+FEY Hi, yes I have missed to show the big hole from the impact in the pcb. Some components were burned out and a lot of carbon black on the chassis and on the board. The owner replaced already the cracked and exploded components. Thanks for watching 73
Another really good video. These videos really help to consolidate my growing knowledge. My recent viewing consists only Yourself, Mr Carlson's Lab and W2AEW Many thanks
Another great repair. Clearly your knowledge and experience pointed you to that faulty resister. I suspect many another service person may not have found it. Look forward to watching your next video.
Terrific video as usual. It must have taken a lot of effort! We all in here greatly appreciate all that you are doing. These videos are like a soap opera you have to watch every day. Ha! Ha! Really great Thanks
Thank you for this video. I just received an FT-1000D with the complaint of low receive audio. However, upon my initial inspection, the problem is dramatically reduced sensitivity, just like yours. I found that it is attenuated by the same amount on all bands (takes -20dBm to reach S9), so the problem is likely in the same "common" path - on one side of the filter bank or the other. I will be digging into it in the next week or so. This video helped me to save time about where to start looking. Thanks again, de W2AEW Alan
It turns out that the fault in the FT-1000D that I had here was different than yours. Here's my video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Uh-VTH7Glpo.html
Just watched this vid with great interest since my main rig is an FT-1000(D). Excellent work OM! Having a comm system analyzer really speeds up repair & testing. Mine is a Motorola R2600 and I find myself using it regularly. 73 agn de Paul
Another good video, thanks for sharing it Peter. Great job on trouble shooting. We can see that the pcb was very damaged, and some one replaced some components with super big ones! That pcb already had very bad days!!! Best regards
Really nice radio testing equipment there, the Rohde & Schwarz one. I pause and stare at it on every video where you use it! I don't want to know how much that cost. I have to make do with an old Philips oscilloscope, some RF probes and a SWR meter that i built myself based on a simple resistive bridge schematic, with RF schottky diodes and analog microamp meters for display. Still, analog meters are awesome. Even when using a proper RF probe a digital meter will lie to you if it is too close to the transmitter you are measuring or its dummy load. The analog needle meter doesn't care much about RF energy around it, it will always deflect to the correct value.
Many congratulations for this repair, I really enjoyed the video. So, the faulty resistor wasn't replaced with the manufacturer's original 33 Ohms, but radio was still ok with the 39 Ohms. 73, Kostas.
+Kostas Hi Kstas, thank you! Yes this little difference between 33 and 39 Ohm in this configuration is not critical and can be done.. Thanks for watching 73
Well peter another success it was amazing what faulty resistor can cause, but you would know that someone has been in and did something just looking at tell tale signs I hope that Radio will be around for sometime to come as they done make stuff like that nowdays :)
As always, thank you so much for the wonderful video, Peter! That really is a fantastic looking radio which REALLY holds its value. Radios like that make complete sense to spend the money to have serviced. 73 de N0BPS :-)
I had a FT-1000D and FT-990 in my contest station before I upgraded to an Icom 756PRO3 and 746PRO, which could not compete with sensitivity and stability.
Peter, another great video.. Thanks.. The only thing I'm missing is that you show your setup. For example, how do you produce a SSB signal in your signal generator? What probes are you using for injecting signal into receiver? How's the setup for injecting this signal and so on. Maybe I'm the only one that doesn't really follow that part? Regards from Sweden..
+Mikael Karlsson Hi Michael, well that is easy. You inject always 1Khz higher as you dialled in frequency on USB. Example f=14.100Hhz you inject 14.101Mhz. That is how it works. The probe is a normal tip with 47nF cap in between to block DC. That s it. Set up: used frequency and my be -73dbm in the front end. Hope that helps.. 73's
+TRXBench Thanks for the info. I guess that it's an AM signal, since you need a suppressed carrier for SSB? In that case, what modulation level do you prefer? Can I use an Oscilloscope probe for injecting signal if I add a small cap in series?
Hey Peter! What was that hack job on the RF board about? The ugly soldering iron strikes again? Thank you for your educational videos, I can't stop watching
Great video as usual but what was the very poorly installed mod above the failed resistor, looked like a cap and resistor added in with a hot poker??? I was hoping you would rework that as well,
I want too know is what is the model number of the probe you are is using? I'm thinking of buying this meter , I'm having same receiver problems with my FT1000D. I can't get a S-9 with -73db input utilizing my IFR 1500S.... So that way I can check the out put of my IFR...
Thanks Peter for another interesting repair video. I learn a lot from your videos. Is there any particular problems that this model has over other HF radios manufactured in the same era? Would be interesting to get your take on that. 73!
@ 30-something minutes (i've been drinking again) "It looks pretty nice" - indeed it does, but when you zoom close up keen eyes will notice that there is a nice little black spot in the middle of the second "3" of the "330" that makes the code of that SMD resistor. That is a clear indication that it is blown. For people watching the video a large 1080p TV, or for people in front of the receiver with a magnifying glass that is. :D Btw, what's up with the horrrible bodge with thru-hole components on the bottom of the PCB, upper left to where that blown resistor is? Did it at least work? I guess i have to watch the rest of the video to find out. I fell asleep last night before the 30 minute mark, maybe i'll be able to digest the whole thing tonight. Either way, nice in-depth video. Thank you once again.
Buenas noche mi ft1000d no puedo ajustar o alinee la frecuencia lo mas cerca que e llegado son 400 hz abajo en el veo principal y el veo secundario si esta centrado en rx pero al momento de transmitir esta 300hz arriba tx quisiera una orientación de saber en donde y como solucionar este problema .saludos 73s y gtazias de antemano
in the minute 22 you are injecting a signal of -137dbm instead of -73 dbm behind the band pass filter and the smeter signal is 9 with a 41 db sinad.how it's possible?
@@TRXLab I'm talking about the Rohde & Schwarz level meter. I'm thinking that it either uses a DAC to drive the analog movement from a digital scaler or, if it has an analog scaler, and ADC to drive the digital readout.
Hi Dene, well that comes literally from around the globe. Some were new, some refurbished and some used. A lab gets permanently adapted to new needs. So it is a kind of evolution. Hope that's answers your question.. Thanks for stopping by 73
Thank you very much for your videos on the yaesu ft 1000 I am 75 years old trained extensively in vacuum tube maintenance. I have a yaesu ft 1000 field and just trying to find out how to fix it case it goes bad. It has been a great transceiver and I will hold on to it until I can't get parts. Thank you so much go to wb8idy.com to see how I use it Have a great day
Hi Brian, thanks for stopping by. Yes the FT-1000 is a nice radio worth to keep alive... I have some videos on the FT1000 on-line hope that helps a bit.. Was on your page and like your motor-home really great stuff. All the best 73
