Re: Yaesu VX-150, FT-60R and SBH-13 Charger Stand and NiMH Battey Pack Life
Be careful measuring high frequency on an oscilloscope, the input capacitance comes in to play and severely?derates the maximum voltage capability.

The two VX150s are spare to my needs and was checking them out.?

Re: Yaesu VX-150, FT-60R and SBH-13 Charger Stand and NiMH Battey Pack Life
You can set the transmit power level. If I remember correctly, if the power level is set higher than the battery can support, the voltage collapses & the radio powers off (& perhaps back on?). That's on ft60s from 2009. YMMV

Re: Yaesu VX-150, FT-60R and SBH-13 Charger Stand and NiMH Battey Pack Life
I know on my 60R there a a auto power saver
?that when you are hitting a repeater on high (5W) power, and you don't need 5W it cuts the power level back. Maybe when you measure your output with a watt meter this auto feature is kicking in. Just a thought.

Yaesu VX-150, FT-60R and SBH-13 Charger Stand and NiMH Battey Pack Life
I have two venerable VX-150s (opened up for CAP use) and an FT-60R and have been charging them on the SBH-13 battery charger. Of late, I have noticed that in high power mode, all three are only putting out about 1.5 to 2.0 watts. The batteries are about 1400-1650 mAh and are very old -- about 4-5 years though little used.
Could I reasonably expect better performance and higher power with similar batteries (i.e., 1400-2000 mAh) and otherwise what would be the recommended course of action to restore the three HTs?
Thanks in advance.

The big question: what unusual conditions did the failing gaskets experience? Temperature?extremes? Mechanical wear? Solvents? Mine are as good as new.

I don't know if it's still available, but years ago I modified
the leather case for a VX-150 to accommodate the FT-60.? It was a
simple mod almost anyone could do.
The mod instruction instructions were on the moderator's web
page.

Both of my FT-60E charge the battery via the DC-In socket however I do not use it. The internal charger circuit is rather very rudimental. There is no end of charge termination implemented. It is basically a constant current source and unlike FT817 there is no timer to stop charging.
