Interesting to hear the squelch issues with cig lighter outlet USB chargers.  I have two that I have used from Daytona Beach to Reno and back without any squelch issues.  It is the Energizer model  #PC-1CA.  I use one for iPad and one for Stratus.

   There are chargers . . . then there are CHARGERS.

   Small variances in their design and construction

   can influence where any antagonistic

   behaviors are noted. Unless the device is

   designed to suppress the full spectrum of

   input frequencies used by potential victims,

   it can emit antagonistic energies in little

   pockets located anywhere on the spectrum.

   So it's entirely possible to find devices that

   don't bother YOUR radios on the frequencies

   you use . . .while still being a nuisance

   to somebody else.



   When qualifying to DO160, and depending on

   the criticality level of that qualification,

   a device is allowed produce greater, potentially

   annoying energies outside the spectrum of 'aviation

   interests'. As you can see below, the limit lines

   for allowed emissions are reduced over frequency

   ranges where important airplane business takes place, and

   relaxed elsewhere.

   Given that no, commercial off the shelf USB power

   adapter will have been so critically evaluated, its

   possible to have one that throws tomatoes at ATC

   but not Ground Control . . . etc. etc. Even

   multiple examples of the same product may demonstrate

   different behaviors.

Yes: nice quality items, but for us this side of the pond expensive, starting at Â£99.00 that's about $150.00

They now have the 4 port ~$190 US Dollars (delivered), and I ordered one of these.

Why you ask would I spend $200 on something I can get for $10 at Walmart?

Noise, noise, and noise.

I've spent thousands of dollars to have quality Comm, and the damn cig lighter chargers wipe all that out with ease. Even kills the FM radio reception.

We'll see if the unit is RF quiet like the guy claims on the website - if it is then it's money well spent.

Yes, based in Cambridge, UK.

So given the time difference, there could be delays in replies.

Wow! The "designer and maker" of the product makes himself available to 

the list and the subject goes dead. Did I miss something?

Well, I do try and put information up on the website, but still happy to answer questions via the forum or via e-mail (address on the website).

I think it's indicative of this list that there is a lot of fancy talk, people go on about design criteria, a lot of theorising etc etc, then someone comes along with positive advice from a professional  -  which puts everyone out on a limb because they know nothing

Gee Whiz, John!



I have a bad day from time to time as well, and it sometimes results in a

post I wish I had kept to myself.  Don't worry about it.

That is a very different impression than mine from being on this list 

for many years.

Some of us use the shared knowledge and ideas here, make our own 

hardware, learn something in the process, and share the result freely 

when it seems appropriate...

I never know whose comment might spark a useful thought or lead to a 

solution!
