Does anyone have practical experience using AA batteries with D size battery
adapters with a Tecsun BCL 3000 radio? If I get a good quality set of
2700 mAh AA Powerex batteries along with a set of D size adapters, how long
will they last compared to a set of D size alkaline batteries?

I was thinking of getting a D size battery charger but the cost of a good
one is pretty high. I've got a very good AA battery charger already, so I
am exploring the cheaper route.

these D size are only 4000mAh, so 2700/4000 is somewhere 0,6 x the time.

I already have a C401FS model Powerex charger for AA size batteries and it
works great. I only use rechargeable AA batteries (2300 mAh and under) for
my small radios and recently purchased Canon camera. However as I
mentioned, a D size battery charger is pretty expensive considering I only
have one radio that uses that size batteries. I was looking at the charger
model you suggested earlier today, and I just can't justify the cost along
with four Powerex D size rechargeables.

I am getting about 4-5 months use on a set of 4 alkaline batteries in my
Tecsun BCL 3000 radio now. If a set of rechargeable AA batteries could last
for a 3-4 weeks under similar conditions, I would be very happy with that.
I was just curious if anyone tried running this model radio with a set of
high-end 2700 mAh AA batteries already and what running time to expect
before they go flat.

A post just received earlier estimated 60% run time compared to regular
alkaline batteries. I thought that would be extremely optimistic.

Don't have that radio but use the AA2D adapters with my E1

Will last only a fraction of the time of "D" alkies, but the recycle
factor could amortize their use versus full size "D"s.

If you're already using and are familiar with Powerex products you might
consider their versatile charger, Maha MH C808M, which will do all your
batteries regardless of what you end up with. http://tinyurl.com/yg53y6
When you switch to exclusive use of re-chargeables for radios, cameras,
flashlights etc., it'll pay for itself soon enough.

Hi Bart,

I'm curious to know, how many hours of play do you get running your E1
off the (I assume 2700 mAh?) AA NiMHs?

Best,

I think (without looking) the batteries I have in it are the
Sanyo Eneloop 2000 mAh, I also use Uniross Hybrio 2100 mAh,
so it could be either. *

Sorry to not have any specific data because it runs on the wart most of
the time and when I've taken it over to the park for quieter listening
I've never exhausted the batteries, although I usually carry a spare
set. It's the camera that eats battery capacity, so the spare set for it
gets used more often.

BB - Well start a Test of the Batteries in the E1 to the point
where the Radio says it need new Batteries and get back to
us with the Answer ;;-}} ~ RHF

- The volume level would be a factor too,

- listening to whatever, well...

Already did a "D" Battery Test in the Eton E1 Radio.

Eton E1 Radio - In Seach of the Low Battery Icon
http://groups.yahoo.com/group/ETON-E...o/message/1031

* Over One Hundred Hours (100 Hrs) on a Fresh Set
of New Alkaline Batteries before the [LOW BATT]
Icon comes on (is visible).

* TOTAL - 103 Hours of Operating my Eton E1 Radio
usingDC Power {Batteries} with 'moderate' (1/4) Audio
Volume listening on the AM, FM and Shortwave Bands;
with the Dial (LCD) Light (LEDs) Turned 'OFF'.

"AA" Battery Run-down-Time Rough Approximation :
Duracell Size "D" Alkaline Battery 15000 mAh -versus-
Sanyo Eneloop "AA' 2000 mAh would come out to about
14 Hours of Listening at 2~3 Hours per Day; and that
would be about 5~7 Days of Listening on a Set of "AA"
Rechargeable NiMH Batteries. The "AA" NiHM Batteries
would have to be required to Recharge about Once-a-Week.

yes it is that simple - e1'ing you all ~ RHF

BB,

The C.Crane Twin Coil Ferrite Rod Antenna is a very good
performing AM/MW Directional Antenna for improving AM/MW
Radio Reception of weak and Distant Radio Stations [DX].
http://www.ccrane.com/antennas/am-an...m-antenna.aspx

For it to be utilized properly you have to both :
Tune-It {Electrical Resonance for a Frequency}
http://en.wikipedia.org/wiki/Electrical_resonance
and Position-It {Rotation in the Horizontal Plane
-aka- Azimuth} - http://en.wikipedia.org/wiki/Azimuth

The C.Crane Twin Coil Ferrite Rod Antenna is designed to
be Tuned -but- Rotation in the Horizontal Plane {Movement
about it's Azimuth} is not a designed-in feature. So you
either have to design your own method of manually rotating
the Antenna Head Inside-the-Room or Electrically Rotating
the Antenna Head Outside-the-House : To get the best
performance out of it.

However There Is Another Alternative {Consider the Alternatives}

The Quantum "QX" Loop v2.0 featuring a 7.5" Ferrite Rod
http://dxtools.com/QX.htm
Antenna Head which Covers the AM/MW Band : 530~1800 kHz.
The Quantum "QX" Loop features both of the necessary
http://dxtools.com/QX.htm
functions of a supperior AM/MW Loop Antenna :
You can Tune-It {Electrical Resonance for a Frequency}
http://en.wikipedia.org/wiki/Electrical_resonance
and You can Position-It {Rotation in the Horizontal Plane
-aka- Azimuth} - http://en.wikipedia.org/wiki/Azimuth

-by- Gerry Thomas [KB4JFM]

Note - Cost about Twice (2X) as much as the C.Crane
Twin Coil Ferrite Rod Antenna -but- for a serious AM/MW
DXers the 'extras' are worth the Price.

Palomar LA-1 Loop Antenna Amplifier Base Unit plus the
AM / Medium Wave Loop Element 530-1700 kHz
http://www.universal-radio.com/catalog/mwant/0445.html
http://www.palomar-engineers.com/Loo...p_antenna.html

Note - Costs more-than the Quantum "QX" Loop Ferrite
Rod Antenna; and has less AM/MW DXing features.

IMHO - For the Serious AM/MW Radio DXer presently the
Quantum "QX" Loop 7.5" Ferrite Rod Antenna offers the
Biggest Bang and Best Value in a Ready-Made AM/MW
Antenna that is Designed for the craft of AM/MW DXing.
