Icom IC-W32 Power Supply Assistance
by Kevin M 10 Apr '16

10 Apr '16

Hello Oliver, Icom HTs are center positive... I have a W32A and the official Icom wall charger (BC-110A) that came with it is 12 VDC 200 mA output and the plug appears to be 3.3 or 3.4mm OD with a 1.0 mm pin, but verify that. (Most Icom HTs use the same size plug, I believe.) There are simple DC cables, regulated DC cables and noise filtered DC cables. I also have a cig ltr plug that runs to an 'empty' battery pack that connects to the HT. I have more battery/power solutions than I need for mine... (Li-Ion & charger, two AA dry cell packs and 10 NiMH AAs with charger) If you want to contact me off list, I can give you details on what I have and discuss a trade or something. =^) 73, Kevin N4UFO I just received a well loved ic-w32 from ebay. I need to get a new battery and a charger for it though. Both are expected. Before I do, though I'd like to make sure it _actually_ works. I have a variable DC power supply I was thinking of either bypassing the battery with or powering via the external dc jack. I don't know what the contact middle contact does though, so I'm hesitant to try that idea. Need to keep the magic smoke in ... Does anyone have experience doing this? Maybe information on the DC jack polarity? The service manual I found online doesn't mention much about powering it up. Any others tips or pointers on the w32a I should know? Thanks for your time.

Re: [amsat-bb] Satellites and Solar (a)
by Edward R Cole 09 Apr '16

I have been thinking about adding solar. Of course up here in the sub-arctic winter nights are long and summer nights short, so seven months of the year solar provides quite a bit. Doing co-generation with the utility definitely reduces your personal utility costs if you do not need battery banks. I already have a standby gasoline generator (6500w Honda) for power outages. Up here its quite normal to have five or so episodes lasting up to twelve hours/each per year. Very nice to be able to push button for electric start and resume normal life when the power goes out. I can even run my kilowatt amp if I desired. We live in the country so have own well and septic so having backup power keeps everything running. Heat is natural gas but furnace needs power for blower and ignition. I inquired at the local power office when recently paying the bill and they support co-gen so all I need to is do my research and save some pennies. BTW I installed solar panels at work before I retired so have a bit of background. Solar insolation on a cloudy day is only 70% down from a clear day. If enough private solar power were built it probably would offset building some of the utility infrastructure in the future. That might even lower the utilities' cost. Up here one utility installed several large windchargers out on a island which has reliable sustained wind which is supplementing the grid (25Mw I believe). There is ample hydro power so solar might depend on the small private sector to build? 73, Ed - KL7UW Nikiski, AK BP40iq Date: Fri, 8 Apr 2016 17:31:21 -0400 From: <jmfranke(a)cox.net> To: amsat-bb(a)amsat.org, Robert Bruninga <bruninga(a)usna.edu> Subject: Re: [amsat-bb] Satellites and Solar (a) Message-ID: <20160408173121.S6MF2.63087.imail@fed1rmwml301> Content-Type: text/plain; charset=utf-8 And the price of commercial electricity will go up because the power companies will still have to support the infrastructure to supply the full load at night or during cloudy weather yet have it sitting idle when as they say "The Sun is shining."

I haven't tried it in a while, but it seemed that the battery UPS units needed a "real looking" mains before letting go of the batteries and getting out of the way. Chaining two UPS units, for example, the second one never kicks in. Has this changed? Will a generator's output be seen as clean enough to satisfy the UPS to let the load run off it, and to recharge their own batteries? Regarding using the electric vehicle's battery, I think the safest way is to limit your use to the "Accessory" outlet, pulling no more than its rated 8-amps or so. Plenty to charge your HTs, laptops, cell phones, flashlights, and so forth.
