>> ... Have you had any experience with any of the batteries that are shown on eBay at cheaper prices
for the FT-60R?

I tend to stick with local dealers or otherwise well-respected battery suppliers for aftermarket cells/packs.
There's a lot of rubbish out there ... with either no one to contact for support, or expensive or non-existent
return policies.

The stock NiMH pack for the Yaesu FT-60R is the 1400mAH FNB-83. About US$36 at Yaesu dealers everywhere.
Properly charged, you should achieve about 1,000 discharge-charge cycles from quality NiMH packs.

Personally, I still use the empty Yaesu FBA-25 AA "shell" and populate it with 2700mAH Maha NiMH AA
cells. That instantly nearly "doubles" my run time (from stock 1400 to 2700mAH).

I further increase my run time by improving my antenna, and turning DOWN the TX power to 2W. I mean,
if you are not making it line-of-sight with a decent antenna at 2W on 2M and 440 - then you're probably not
going to make it at full TX 4-5W power. (Example: I worked the ISS FM voice when it was a few hundred
miles downrange at 2W and a handheld tape measure beam.)

I FURTHER increase my battery run time by using a headset or speaker-mic. What eats up batteries? Keying
the mic and transmitting, and turning up the VOLume of the received audio. What is the first thing you do when
you have a shoulder-mounted speaker-mic or are wearing a headset? You turn the VOLume DOWN.

SO ... Just using the stock 1400mAH battery packs - there's how to more than DOUBLE time between charges:
improve your antenna, turn TX power down, and use an audio accessory!

There are Li-Ion packs for the FT-60R. The advantages pf Li-Ion are that they will maintain their charge longer
than NiMH, and they perform better in freezing temperatures. And they weigh a little less than their NiMH
counterparts.

Personally, I do not charge up a radio and put it away for months - to be used later. And I do not live in
a frigid region. And the minimal weight difference? Nothing to get excited about.

BUT - quality Li-Ion packs will only provide about ONE-HALF the total number of discharge-charge cycles
as NiMH provides.

And so it goes ... Happy 2019!

Clint, thanks for the good info, I also like your shortcut version of the FT 60 programming, much easier to understand than the Yaesu book. Happy New Year to you . Jim W5JJG

Thanks for the kind words.

YES - I digested that FT-60R 84-page manual, and came up with a half-page
of steps to manually program it ... (grin)

All the info is USUALLY in one's owners manual to manually program their
radios ... but it is SELDOM on Pages 1-3. Steps needed to accomplish that
very basic task might be "hidden" ...

So while I was working at HRO-Anaheim, I wrote a few "quick programming
guides," covering these radios - in addition to the FT-60R:

KENWOOD Cheat Sheets
One-page programming guides for the TH-G71A, TH-F6A, TM-271A, TM-G707A,
TH-D7A, TH-K2AT, and TM-D700. (106 kb .pdf)

ICOM HT Cheat Sheets
One-page programming guides for the IC-R20, IC-T2H, IC-T7H, IC-T81A, IC-T90,
IC-V8, IC-U82, IC-V82, IC-W2, IC-W32, IC-Z1A. (631 kb .pdf)

ICOM Mobile Cheat Sheets
One-page programming guides for the IC-207H, IC-208H, IC-706, IC-706MKII,
IC-706MKIIG, IC-910, IC-2100, IC-2720, IC-V8000. (590 kb .pdf)

They are all available on the DOCS page at - http://www.k6lcs.com
