Author Topic: TS-830s on 12 volts?  (Read 7183 times)

I own a Kenwood TS-830s and I would like to have the ability to power it with a 12 volt deep cycle battery. The manual says it is doable but I haven't seen a 12v power module for sale anywhere. I do have one that is for a Yaesu ft-101 and was wondering if that would work with the Kenwood.

Any info on this would be appreciated.

I would like to have this for Field Day and a remote set up.

I really don't want to use a generator or an inverter for this application.
Thanks, Don

Plug & Play.... No. Modded? Maybe. You'd be on happy street faster if you scored a ~500 watt 12 volt DC to 120 AC inverter like the RV folks use.

Be aware that tube rigs can pull something like 25 amps or better when running through an inverter. Depends on the mode, not as efficient as a sand rig.

I have several inverters.

I am hoping for info on the 12 volt power module that the manual refers to or a suitable replacement.

Ah!!  TS-830s  king of the Hybrids. 
I doubt that many of the 12 volt modules were ever sold.  The folks that bought them surely
were the kind of hams  that would hang on to them.  Something a bit smaller like a elecraft
K2 would do about the same job depending on the modules it has and would draw a lot less
current particularly on receive. 
If you are set on finding a power invertor module from Kenwood  well

Good Luck

I believe all of the TS-830S (K type) transceivers sold in the U. S. had a hard-wired AC line cord. There were 220/240 AC versions that came with a 12 pin male connector on them as shown in this link: http://lh5.ggpht.com/-7KPq4EIuF1c/Syl_8TaebEI/AAAAAAAAAlY/sKb3vnMoVKA/DSC01042.JPG

The Kenwood DS-2 DC to DC converter was designed to plug into this connector. It was designed to work only with the TS-830S (W type only).

An inverter (12 DC to 120 AC) would be your best choice unless you want to diddle with the internal power supply wiring, drill a hole, add a 12 pin connector, etc. unless you have a TS-830S (W type).

Hi Don,

Get a used APC SmartUps SU series off ebay, approx $40
they show up all the time without batteries.  save on shipping
and feed it with your 12V battery.

These can be cold started (w/o any ac present).

The SmartUps also produce full sine wave AC, many
of the inverters out there use a modified or square wave
and the transformer in the radio don't like that.
