Yaesu FT-290R internal battery power?
I have recently become a licensed radio amateur in the UK. I have acquired a few radios and my main one at the moment is a Yaesu FT-290R. I have been running it off a 12v regulated power supply just fine up to now, but I cannot get the 8 internal "C" cells to power it.
I've put in 8 new Cs, correct polarity.
I've looked at a .PDF of the owner's manual online, no help there.
Any ideas? I really want to get into SOTA and WOTA, but with no portable PS I can't.... :-(
By the way, my callsign is M6AIM, mike, six, alpha, india, mike.

You could, I suppose, run it in the car ?
I'll take a wild guess and suggest the switch that switches between external PSU and battery, and which is usually inside the connector for the external supply is damaged - should be an easy fix.

Do you mean the block diagram on P24? If so, I can see the 12v battery, but no switch or J5? you've lost me....
Thanks BTW :-)

The rules of SOTA say that you cant use a car, must be on foot when the summit is activated and using battery power.

Still no luck with this, I'm taking it in to the local club to see what can be done. It's on loan from another amateur so I can't really go attacking it with a soldering iron.

Does the meter show the battery to be good when you test the batteries?
Here's a link to the manual if you don't have one.

I have seen the manual. Thanks anyway.
I cant even turn it on (power it) with the battery. That's my problem. :-D

I don't geddit... AGH, for some reason I just can't understand the diagram. Hmmmm, can you explain?
See the batteries ? Are they the ones you have definitely replaced with new ones ? Presumably they are. You see the tip of the red arrow ? That's pointing to the switch INSIDE the "ext. DC" jack - where, I think, you are currently plugging in your power.
The 'V' shape on the end of the switch, next to the black up arrow is lifted AS you plug in the DC. It DISCONNECTS the batteries as you do so. IF that switch is faulty, it is JAMMED OFF, and even when the plug is removed the switch DOESN'T let the batteries work.
