- To: info-hams@ucsd.edu
-
- I am interested in information about Rayovac "Renewal" reusable alkaline
- batteries.
-
- They look like a good deal, since the batteries themselves are similar
- in cost to ordinary alkalines, and unlike other rechargables have the
- full capacity of an alkaline battery , at least for the first few times
- the battery is reused.
-
- Does anyone have experience with them or understand how they work? Is
- it possible to charge them yourselves, or are the specs for doing so
- being kept quiet by the manufacturer?

- there they are! Anyone know just how it is done? A little dropping

- A friend of mine just got a TS-50 this weekend and is having the identical
- problem in his Ford ( don't know type). He has confirmed that is noise
- coming from the fuel pump. He pulled the fuse on the fuel pump and all
- noise went away. He says that Ford is aware of this problem and he
- heard that a special filter was available. But as of yesterday afternoon,
- the local dealerships said that they would "have to look into it" and
- played dump. I hope that helps narrow it down for you.

- How about the FCC giving the VEC's a list of new callsigns to be given
- to successful examinees on the spot, and the VEC's just fill out a form
- with the new call holder's name and address? Maybe some VEC's might let

- Similar security as that with the present paperwork. Only thing is that

- that particular form with it printed on.). Shouldn't be any major problem.

-
- Ahh yes, a caveat to those thinking the same thing. The Panasonic
- 900 mAh cells use foam electrode technology. In short, this
- means that the internal resistance of these cells is substantially
- higher than we are accustomed to for NiCds.
-
- What this means: During transmit, when you are drawing an amp,
- the voltage supplied by the pack will be less than you expect
- due to ohmic losses.
-
- I have foam cells, and yes, they have great capacity, but they
- do suffer from voltage drop during transmit, which means
- that your TX power is lower than it should be.
-
- Do an experiment if you have both the foam cells and an
- original NiCd pack in good condition. During high power
- transmit, note the DC voltage using the handy-dandy built
- in voltmeter and note the voltage drop between Rx and Tx.
- I think you will find that the drop is double with the foam
- cells -- at least that is what I find with mine. Note
- that part of the additional drop could be due to the fact that
- the FBA12 uses spring contacts while the factory pack uses
- welded terminals.
-
- If this is a problem, Sanyo makes the KR-800AAE, 800 mAh
- sintered plate cells, which have 12 mOhm internal impedance.
- (I have no connection to Sanyo.)
-
- Glad to hear that this worked for you though. I have been
- using NiCds in the FBA12 for quite some time. At $50 for
- a factory pack, and $5.00 for a set of 6 cheapo NiCds, you
- can't lose.

- Jeff, you'd better read the footnotes on those allocations (97.303 b thru
- q). I've added most, but I'm sure I missed or messed up a few in the
- ultra-fine print of Part 97. I'm still using the 1991 edition, since the
- GPO unfortunately has not yet shipped our orders (placed in November '93)
- for several copies of the 1993 printing.
-
- These are NOT "Amateur Radio Bands" in the same sense as the lower
- frequencies. In general they are NOT allocated amateur worldwide or as
- primary use. The only amateur allocation at 222-225 MHz only happened
- because the hams made so much noise about the piracy of 220-222 for
- commercial interests, who now have lost interest in that segment
- completely.
-
- The FCC just started granting PRIMARY licenses in the 902-928 MHz band to
- data and information services, so you can kiss it goodbye before 2001 rolls
- around.
