Fw: [QRP-L] Solar power for the rig?

WA0ITP

#2923

I reposted Mert's sage advice here because some of us may be bringing solar 
panels to Brutus.  Mert is a Four State member, regular Ocon attendee and has 
published many articles. All that plus being a great guy.  Thanks for the solar 
cell charging tip Mert.

| Hi Terry,
| I have  used both PWM and pass transistor (linear) control for my solar
| panels.  I prefer the pass transistor because it causes no R.F.
| interference.  Yes, it needs a heat sink and dissipates some power but all
| power is free anyhow.  My pass transistor is a 2N3055.  Of course, I am only
| charging a 7 Ah battery so only about an amp max.  But I guess if I need
| more current, I will parallel some transistors or get larger ones.  The
| circuit is the same as any linear regulator power supply.  Simple and
| trouble free.  I don't like to deal with RFI from the switchers.
| Have fun.  72   Mert  W0UFO

| I have been considering a small solar cell powered setup for the shack.
| In the process of studying the possibilities of how to do it, I have
| seen references to charge controllers using PWM saying you can turn them
| off for communications periods or they have minimized the impact on
| communication installations.
|
| I'm getting the idea they are pretty noisy electrically.  I have no
| experience with them.
|
| Is there anyone out there who has used a solar panel or other
| alternative power source and a PWM charge controller that can give me
| some idea as to how significant it is or is not.

| Terry, KQ5U

#2922

Hope to work some of you tomorrow. I'm even going to get on the mic for a stretch tomorrow!

I'll also be posting on the QRPSPOTS page when I am operating QRP.

I'll be happy to exchange 4 States info for those working on the W25 awards.

Come Join us August 24th and 25th to celebrate Burlington, NC railroad origins as we operate from the Norfolk & Western Caboose #518654.
Special Event call N4W, check it out on QRZ.com
and http://www.cwfun.org/funspots/n4w/

We'll have operators on SSB 14.265 and 7.235 +/- QRM

The main show will begin at 1600 UTC from the Caboose.

CW operations on 7.055 and 14.059.

That's (12:00 Noon Eastern) We'll have QRP and QRO stations on air.

We'll also have a spotting and sked page at http://www.cwfun.org/funspots/n4w/

You can pop in to say hello or find us and request a sked/frequency.

A Special Event QSL card will be available with SASE.

Hope to see you there,

Hi folks....

Perhaps I have lost my limited "memory chips" after 50 plus years as a ham but,I have recently built the 4S-Link but now can't figure out how to connect it between my IC-703 plus and my computer!  I am also at a loss to understand why there is no power supply requirement even thought it contains several transistors.  What is this old geezer missing other than his mind? :)   Milan K9HDX

Phil,

That is DAMN neat!!!!!!!!!!!!!!!

For a transplanted OKIE that above is quite a statement but TRUE!  Not only a OKIE but a dyed in the Orange and Black of a OSU cowboy:-)  I still love the orange and black of the Stillwater cowboys and root for them UNLESS they are playing the Jayhawks.  My mother attended Oklahoma A&M, I attended Oklahoma A&M(in fact it became OSU while I was in attendance), my daughter attended OSU, my son graduated from OSU and then earned his doctor of jurisprudence degree from KU.  So you can see that it was a tough conversion for this ole cowboy:-)  Patsy and I only watch one sport on TV and watch it together from tip off to final buzzer and that, of course, is Bill Self's KU basketball!!!!!!!!

#2918

Hello All. [Friday, 8/23/13, 9 AM] What a delight: Had my cup of Joe; went
downstairs, turned on my HF CW radio station; heard WW9E calling CQ and
answered him. The first thing Pat sent in Morse Code was, "Ok Phil, Rock Chalk
Jayhawk! Hey, I grew up in Desoto." Pat now lives in Coloma, MI, and gave me
a strong 58N report on my 10 watt signal using my NIVS dipole antenna.
How neat is that! 72, Phil, W0XI.

HI Johnny,

I see that we are near neighbors; you in Topeka and I in Lawrence. Funny
that I could hear all the guys below in 7:30 Net but barely heard you enough to
make contact, closest in to me; and, I was using my new NVIS antenna.
I'm guessing that an iono-sound would indicate straight up reflections from
ionosphere were not working last night and I heard you on ground wave.
I switched to the vertical and didn't hear you on that.

I'll do a search to see if there is an ionosound service, recordings for our area
anywhere on the web; would be interesting.

Glad to hear it wasn't just me with the constant S-9 noise all night. Was beginning to wonder if I had a local noise problem.

Heard a few peeps on 7.122 and that was it.

Also monitored the PSK Net and saw K6QKL go down the waterfall ONCE and that was it. Nothing else copied.
