TS-50S review
 | N2MDV | December-10 2023 |
After having the 6M TS-60 for a number of years, and loving that rig, I didn't really need the TS-50, but wanted it to compliment the TS-60, and to have a good back-up rig. AES had one more AT-50 complimenting auto tuner for this rig, so I bought that out. The only thing that was wrong with the rig when I'd gotten it was a dead Li Memory battery. That was easy enough to replace. Also, I've opened up the rig for 60M operation, which it does well. However, the AT-50 auto tuner will not do 60M. (The auto tuner in my TS-2000X doesn't either). So, I use a manual tuner for that band. I agree that the NB (Noise Blanker), isn't that effective. I never really did understand what that AIP feature was for on RX, but I used it like it was a 10dB attenuator. RX itself is pretty good.
It's got better ears than the TS-2000 and my Icom IC-7000, and way better than the Yaesu FT-857D. AM TX on this rig is quite good, and I've received compliments on it. And that's on the stock mic. What's strange it you have to drop Mic Gain to Low for that. (Same with the TS-60). Only gripes? TX power levels are 10W, 50W, and 100W, non-continuous. Not very effective NB. And not really great for portability since this rig draws over 1A on RX. However, this rig will work in -10deg below Zero F. One big plus is all FM features are included for 10M FM repeater work, splits and CTCSS. Not many HF rigs in the early 1990's had this. 100 Memory channels is nice as well. It's a keeper.

Be aware, the TS-50S is now getting 25 - 30 years old.
TS-50's suffer from poor soldering of their DDS circuit boards which causes intermittent Tx/Rx operation, reflow the solder on the DDS boards generally fixes this issue. TS-50s also suffer from leaky electrolytic capacitors, these capacitors were manufactured in the late 1980s with a stolen electrolyte formula (you can Google this to read the full story), the formula was incomplete resulting in an acidic electrolyte which eventually eats through the can of the capacitors, leaks on to the PCBs and destroys the PCB tracks. Kenwood were not the only electronics company to be caught up in this leaky capacitor problem around this time.
Keep in mind that the TS-50S uses surface mount electronics so repairs need some skill and a steady hand. You will also need the PCB card extension kit if you are doing in-depth repairs on this radio and those kits are now hard to find. My TS-50s needed the solder reflow on the DDS boards, it then provided a number of years of good service in my car, eventually the capacitor issue killed the radio.
