Ham Radio - Kenwood TS430S repair and CW filter install

[@w.rustylane5650]

Well, Kevin, it's about 4 years later and I no longer have my Kenwood TS-430S; I now have a Yaesu 991a and I love this radio. The old Kenwood served me well and I gave it to another ham. I had the matching power supply (PS-430) and see that pigtail fuse on the board toward the rear, you have to take the covers off the ps every time you need to change the 12 volt fuse. I mounted a fuse holder on the back of the supply and ran heavy wires from the board to the fuse holder. Now you can change the fuse without taking the ps apart. Cheers & 73 from W Rusty Lane K9POW in eastern Tennessee

Hi,Kevin Ive,recently bought another KenWood TS-430S ,And i must say its probably the best H F Radio of its time when it was made though im only still a technican class ham on 10- meters it really does its thing and for DX ING too,and on just 100 watts of TX Power from the radio it really performs extremly well ,,my friend back east got me hooked on this radio,and now ive had 3- TS430-S KenWood radios,this one wont be for sale, it seems to me that this radio is getting very hard to find,Ihave to install the AM Filter when it arrives your video on here will be very helpful to me for the installation of the ,AM Filter for my KenWood TS430-S ,Thank you for a great video,Dave KD8HMH.And i enjoy my 430 .

Good information. On old parts and boards if you carefully clean them with a eraser, some alcohol, then treat a little liquid flux The solder will quickly bond so you don't overheat the items. Learned new things on your video.

Very nice repair Kevin. I wish I still had my 430.

[@PeterHolford]

Modern radios board mount mini components. No chsnce with a soldering iron.

Hi Kevin, Nice repair. Glad you were able to find a replacement switch without having to source one online. 73 WB3BJU

Perhaps the guy meant the AGC was mot working? I did not see the meter move when receiving signal generator tone. Good video and good work! Keep the old gal running. Love it.

[@loughkb]

The signal genny was just emitting on a small antenna, not enough signal to tickle the meter. It does work. After talking to him, he told me he had the same problem with his backup rig and found an issue with his microphone or audio routing. Not the radio after all.

[@w.rustylane5650]

You know, if you were repairing that for me, I'd be happy with a SPST lever on/off switch and you wouldn't have those kinda headaches trying to find a click switch. But then, that's just me. I think a lever SPST switch would suffice for my tastes and it would be more reliable than a click push in/out switch. You forgot the AM filter after moving the white wire. You should have tested that function as well.

Hi Kevin, I'm happy found this video. I follow it and expected ALC problem because i had similiar in my 430. Tried to increase mic gain but no swinging at all. Your suggestion please.

[@sunnylandcamper]

just picked up the same radio today

[@MrPerrey]

Nice service work Kelvin! But one question, whats about the UBitx build, announced but never started?

[@loughkb]

It's coming. I've passed it on to a new ham in exchange for a guest video of a new hams first kit build. I thought that would be an interesting subject.

[@arctos49]

Hmmm, seems to me that a usual mike gain setting for SSB is around 10-11 on the control. Either the circuit is low in gain or the mike is not as sensitive as they usually are. I'm receiving a TS-430S later this week so I will be able to see what it is normal on my rig. Good video especially about the filters as my rig will be loaded with them and I am thinking of removing two of the narrow ones (SSB and CW and selling them. This video gave me a good idea about access. 73, Bruce K6RQR

Hello Kevin: I have a Kenwood TS 930 SAT and the power supply switch went bad on me too, !! I wound up having to replace it too !! My switch was a DPST variant though. and yes mine was a tight fit too and wound up putting in additional insulation too !! so far so good ! I found my replacement on EBAY and I ordered 2 of them.

[@BEdmonson85]

Hey Kevin, have you ever tried a product called "Liquid Tape" for odd-ball shaped parts that need insulating like that power switch? I used to use it at a previous job I had, insulating ground connections on vehicle chassis'. It works a treat and you don't have to worry about it falling off after a few years of heat, won't leave that nasty sticky residue behind like vinyl or pvc electrical tape either if you do have to remove it. It just peels off with a little effort and leaves a nice clean surface. It's a bit pricey, about 8$ for a 4fl. oz. bottle, but the bottle lasts near forever!

[@loughkb]

Yes I have. Actually what I should have done, was to throw together a 3D printed cap to snap over it.

[@space12127]

Hiii, my dad and I just recently found that exact Kenwood 43O6. It came with the microphone but no power supply, where can I get one? We want to give it a nice home

[@loughkb]

Maybe on ebay?

[@jeromegrzelak8236]

Man did you luck out on that switch install hope it will handle the current in the future 73

[@loughkb]

It came out of a repeater power supply designed to provide 20 amps at 12 V, so that's around 2-3 amps nominal on the AC side. The same as the supply it went into. It's a match.

[@robbsanderson3572]

Hi Kevin keep up the excellent work. Do you still do any bench repairs? If so, I have an old Yeasu FC 107 tuner that periodically shorts out when I used it. I bought an MFJ 948 tuner and it works great. I’m so glad i did.

[@loughkb]

Hi Robb, sorry, but no. I don't trust my hands and eyes when it comes to working on other people's gear any more.

[@dylanmaniatakes]

what is that empty filter slot? im curious I see SSB,AM and now CW is it FM?

[@johnbuckley683]

The empty slot is for a narrow sideband filter. YK88-SN

[@diverbon911]

Awesome work Kevin! De KX4EZ

[@glenngoodale1709]

Totally awesome video 😂😂😂

[@okhamradio]

Good job!

[@space12127]

Thank you

[@r.w.leblanc6326]

Excellent Video

[@pathopkins4500]

Good job re purposing used parts .... lots of time now days you cannot find replacement parts for even new radios =) Kevin ... you might try making a new plastic plunger part the switch uses with a 3D Printer .... it seems to be a good replacement part to offer =)

[@loughkb]

Too fine of detail for 3D printing. You'd need to do injection molding to get that small of detail with any strength.

[@johnhiggins4698]

Hi Kevin! I’ve looked back over the videos for finals repair you did on a Yaesu dual bender...no luck. I’ve got an FT-7100 that began to degrade on transmit-distortion, etc.-so it’s been sitting in a box awaiting the day when I might try to work on it. If you’re interested, I’d be happy to ship and pay for your time? Love your stuff! 73, John/N6VTS

[@willgilliam9053]

Hey Kevin, was that part no good for your 3D printer?

[@BEdmonson85]

I imagine, that he probably just wouldn't want to chance it, just in case. When you're repairing someone else's stuff, it's not really an appropriate time to experiment with parts like that. Of course, that's just my opinion. I'd hate to hear 6 months later that my 3d-printed part failed and the customer has a bum PSU again.
