Energizer Lithium AAs - Anyone try yet?

Has anyone tried the Energizer Lithium AA batteries in the 246 yet?
If so, how long did they last?

Thanks in advance,
Chad

Go to this URL and try some of the soundbytes.

One of them should be what you're hearing. My guess is AES
encryption. Could also be inversion as mentioned by the others.


Re: In-Unit Battery Charging Cycle

n5cwm <n5cwm@...>
 

I did some basic tests with my Volt-Ohm meter recently.

With the switch in the battery compartment set to ALKALINE, the
batteries are not charged yet the unit is powered. Set to NiMH then
the batteries are charged as expected.

Anybody else find this to be the case?

As such, if you plan on using it with the power supply on always,
just move the switch to ALKALINE.

Plan on using Davis RF bury flex coax.
In general will the coax be so stiff that you will have to lay the
scanner on its side when connected?
In other words will the stiffness of the cable not allow the scanner
to be upright?
Is there and cradle or base you could set it in so it would
stand up?

I know lame queations.

Take a look at one of these stands:

You can also look into buying or builing a cable assembly to take
strain
off the BNC connector, such as this:

Thx for the great idea about the jumpers.
Does the jumper cable have to match the main acble its attaching?
I mean does the main cable and the jumper have to be the same coax?

Thx.

Well, there are a couple of approaches, and sometimes you have to use
more than one...

Try looking them up in one of the online databases, like
RadioReference.com. That will usually indicate the system type.

Listen to the control channel -- that buzzing sound. The different
systems use different modulation methods, resulting in different sounds.
I think there are some recorded samples online that you can compare to,
but I don't recall where offhand. Anyone else know?

Try programming a minimal test system, with just the control channel in
it. Then hold on the control channel, and see if the scanner decodes it.
(You'll see an indication of the active talkgroups on the display, even
though the scanner won't switch to the voice.) First try it as a
Motorola system, and if that doesn't work try EDACS, etc. Since you're
only putting in one frequency, it doesn't talk long to reprogram it.

Anyone else have any other tips?

You could try a suction cup mount that mounts the antenna on the inside of the windshield glass. I would rather use a mobile antenna, but this might be a compromise that will improve your reception.

this is more of a general trunking question rather than a question
exclusively for the bc246t. let me first say that this is the first
trunktracker that i have owned. i have scanned for years but could
never justify spending $250 for my 4th scanner. well i finally bought
one and i am glad i waited until the bc246t. i carry it with me to
everywhere but the shower. anyway. my question. i have noticed that
talkgroup id's are separated by 32 (or another number); for example--
18300>18332>18364etc. Why do they just not go 18300>18301>18302
etc. ??? thanks in advance
Within the trunking system software, the talkgroups are in hexadecimal numbers.

The talkgroup IDs you see are decimal representations of the hex numbers, and will always be divisible by 16
So talkgroup E4F0 would show as 58608

Hi, any tricks or tips other than using mobile antenna to get better

Thank you.


Re: talk group id #'s

Clayton kg0vp <scankc@...>
 

I assume you are talking about Motorola ID's. They are actually seperated by 16. The other numbers in between are used for the special conditions i.e. emergency, patched, etc.
Depending on how the system is set up, they may not all be used in order. You may see 16, 32, 160, 320, etc.

Thank you for your efforts Walt.
I will keep the results of your tests in mind when re-charging in
unit.
I had noticed that the batteries / case did warm up considrably when
charging overnight.
As I always say the best way to muck up a good argument is with
facts.
I believe that some chargers work on reading the battery temp via
some form of sensors, but could not see how it could be done with
ordinary re chargeable AAs.
BTW W.R.Suite's 246T Manager program (thanks WRS) found in the files
section shows battery voltage, if you had not already pick up on
that.
Given that it appears to be a timer on the charging circuit am I
right in assuming that smaller capacity batteries than supplied
could be over charged and larger under.
Thanks again for posting the results of your tests.

In-Unit Battery Charging Cycle

Walt Bilofsky
 

I ran a few tests on the in-unit charging cycle, and saw the
following:

o The charger runs about a 15 hour charging cycle, and then cuts off
completely.
o Turning the unit on and off does not affect the charger. If it was
off, it stays off.
o Unplugging and replugging the AC adapter begins the charging cycle
all over again. It looks like it does not sense the battery charge,
just runs for 15 hours regardless.
o During the charge cycle, the battery temperature rises past 100
degrees - probably a bit higher.

I tried two charging cycles, first with partially discharged batteries
and then with the charged ones. The unit applied a charging voltage
(rising to about 2.92v) for roughly 15 hours, and then tapered down,
leaving the batteries around 2.57v. That voltage didn't change when I
unplugged the AC adapter, so apparently the charger was cut off
entirely.

The manual says a full charge takes 14 hours.

During the charging cycle, the battery temperature got up to 101
degrees, measured with the cover partially ajar (to accommodate the
temperature probe). With the cover on it'd be higher.

Uniden tech support told me that leaving the charger plugged in and
the batteries in would shorten battery life somewhat. I saw it a
little different.

My conclusion is that if you are using the unit for a base station, it
does not hurt to keep the charger plugged in all the time (except for
running up your electric bill a bit). If you only plug it in when you
use it, it might be better to remove the batteries.

If you mostly use it on batteries, then charging for 15 hours after
every use will give the batteries more of a beating than charging when
needed. Can anyone else quantify how much that would shorten battery
life?


Belt clip mod

Brian S <yahoo@...>
 

The belt clip for the 246 as supplied is a bit difficult to slip on
your belt.
The tongue is not flexible enough.
A small fault but a annoying one.
A solution is to fit sprng washers under the two screws that attach
it to the unit.
This allows you to spring the tongue open by excerting pressure to
the top ofthe tongue to open the bottom of the tongue as you slide
it onto your belt.

Rich,

One of the option settings for each trunked system you compile in the
USAD software is "search" or "scan." The default is "search."

Next time you reprogram the 246T, set that option to "scan" for the
trunked system you are referring to. That way, it will load
correctly each time you reprogram.

In the meantime, the scanner will retain the setting you have (I'm
presuming you have already set the system to scan via the keypad).

read the manual
take your time, be patient

it is set up in a hierarchy

group

1 channel == numerical (usually 5 digit) designation

Re: Trunking and Conventional

Rob Dale <rdale@...>
 

You program a new system, select the trunking type (Mot / EDACS / etc.) and
then enter the frequencies. Set the system quickkey to 1.

You program a new system, select conventional, enter the frequencies, and
set the system quickkey to 1. You do not need to use group quickkeys if you
want them received all the time.

Hi, how do I program Trunking and Conventional frequencies
into system 1 and group 1?


Re: Trunking and Conventional

Joe M.
 

You can't. Program a system as conventional and another as trunked. If
you want to 'lump them together', assign them both to System Quick Key 1
and you can use them as one traditional 'bank' - enabling or disabling
them both together.
