• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Yes. It will go with me to Arizona first to be used in my 5th wheel. I did buy a President Washington radio the other day. Just waiting for it to be shipped to me.
so what is happening with the old 5555 N II???? are they giving you your money back??? exchanging it??? let us know... did you buy the Washington from them???

Can run 12V radio straight off house batteries given inverter has some capacity.

So, unless you’re going to run wattage higher than an export, you’re already set. Amp draw for a KL503HD @ 150W limit would need to be figured (fuse rating) to play on SSB with a portable exterior antenna (tripod, extending mast, in a tree, etc). I’d use a 100’ coax run as a baseline.

A travel trailer is a mobile. Wire to POS (fused) and can run NEG to BATT, or, to trailer frame ground (my choice) where BATT also ties (same as with my pickup).

Granted that this can limit location of radio rig. It suits mine as both inverter and lounge area are in the bow.

If you were going straight to the Utility park power 15A receptacle then need to think about how to run. Marine-style flush-mount receptacle would seem best. Maybe you know an electrician.

— Astron lasts forever (seriously heavy).
— Mega-Watt inexpensive and robust by report.

While at home (now) would be a good time to start the “interfering RF” search. LED, and other devices factory/installed (circuit-by-circuit) versus being on the road and away from home & shop. RV electric as you know is kinda weird already. I’d want to run anything which is thus powered while at home. All appliances, etc.

It’d also be the right time for a concealed coax run to a location for vehicle exit. Reasearch whole topic of RV radio service.

Yes that is for sure. I run 2 Morningstar 60 amp MPPT Charge Controller on my solar set up. I have 1400 watts of solar panels on the roof. The controllers are commercial grade with no fans running. They have worked well keeping the batteries charged for the PLC when I worked on the North Slope of Alaska. I will try them out on my radio soon. They have never gave me any problems with other electronic equipment.

I’m impressed. Always wanted to run the Al-Can, but the Heavy Haul Road is another matter.

Royal Dutch-Shell sent my Dad to Prudhoe Bay in December of 1968. Helluva place to spend Christmas. A film needed for investors & bankers.

Fly-in on an L-100 Hercules with a CAT bulldozer chained down as payload. A landing where easing into the thrust reversers was advisable (hearing chains snap their slack).

My son drove the 5,500-miles from D/FW to Anchorage a few years ago also in December to initiate the family move. Solo SUV with the radio rig I’d given him. It’s another thread topic to discuss what radio service works once into Canuckistan.

RV radio choices can be several. And, antennas. So 15A dedicated service with a P-S looks good also as you ain’t the usual rookie gone to watch TV in a warmer climate for winter (Quartzsite, AZ).

I run a 3000 watt Magnum inverter/charger. Also have a 5500 watt generator which I rarely run. I have a small 300 watt inverter wired into a dedicated outlet for my TV and Starlink satellite. I will run separate 12v dc lines from the battery to my radio soon. Just been to hot lately. For the most part my solar is all I use in Arizona unless we get 3 or 4 days of cloudy weather. I don’t camp in rv parks. Usually just out in the desert somewhere far away from stupid people!

Michigan gets hot?

Forecast today for NC Texas is 100F+ with index of 110F expected. In the shade. 85F and 80% Humid at 1000.

I haven’t run my radios on the minimal solar & house battery system I have. Someone out there will be able to advise.

I can say that in big truck we never run any radio of consequence without either main engine or APU also running. Start system only, no house bank. A “no start” of a 15L Detroit generates participation ribbons daily in this country.

Lacking a genset I’d be running the Cummins on high idle to play radio if without shore power.

Motorhomes (like marine setups) have separate battery banks. Us trailer guys pay a little too much penalty for such though in your case it might be worthwhile given one can track consumption as a guide.

Yup, it’s extra bonus warm here in Richardson. Heading to So Cal today and nice ocean breezes. And reliable RFI free Astron power supplies, although I use a Powerwerx SS-30DV here.

Yup. Been 90 plus with all the dam humidity. Here lately we have been chocking to death from all the wild fires in Canada

Fires & Floods.
Distant Early Warning.

Can’t honestly rely on so-called “official” warnings or advisories or actions. Ones fellow man is last resort.

Can I hitch & go? Or do I have to abandon my home on wheels? What roads and what bridges?


Having fun with a first class radio & install is how one occupies the interims.

A quote from early last century defining industrial warfare also applies to mobile Citizen Band: “Long periods of boredom punctuated by moments of extreme stress”.


Once it finally sinks in for the hard-heads that you’ll be abandoned (Lahaina, Swannanoa, Palisades, Kerrville, etc) CB will again be seen for the low-cost, high-value it represents. A no-compromise system.

And as on-air AM malefactors start to get their comeuppance to change the hard-heads failures in imagination due to Hollywood and what they “think” [sic] CB is today. (“Oh, no, I heard a cuss word!”)


I’d carry a Mega-watt (example) as who knows . . . maybe we’ll want to set up at a motel room. Someone’s back porch. Be a shame couldn’t use a system for lack of a $50 component.

So power supply can be seen to apply even if it isn’t first source of power for RV or Marine. Same as painters pole & balcony antenna isn't first choice.

Take a look at the Powerwerx SS30 power supply. I’ve been running two of them for the last eight years and they’ve been flawless. Good price, small size, quiet.
I have three Powerwerks SS30s and two are at HF remote sites running 24/7 for the last 9-10yrs and no RFI or reliability problems. Two of them were bought used off eBay. But I would still recommend Astron first.

Ah yes Quartzsite, Arizona. Been there many times. Dome Rock Rd camping is a homeless haven anymore!

I have drove the Al-Can Hwy 71/2 times. I lived in Big Lake, Alaska for 7 years. Toad River in BC has found memories for me.

Spent many months/years in and around Prudhoe Bay. I have driven from Fairbanks up the haul road many time to Prudoe Bay. Watch out for the Caribou! Great memories!

Thx in the above for the several recommendations of the POWERWERX SS30.

I see it’s offered with several accessorial options which increases desirability. Small footprint = RV-desirable.

25A continuous covers most everything I own up to and including an ft450d.

I believe I’d need to run a dedicated circuit as RV tends to crowd what’s available.

Would also fit right into one of my transport cases for “off-site operations”.

It is a small little thing. It looks like it would be a great option for and RV. Space is at a premium! Where I want to put my radio I only need 10 feet of wire straight to my battery bank. I will let my solar do the work, but at home it would be a good option for me too. Seems to have good reviews also.

I never would have guessed that was a 25A supply. Definitely great for applications where space is at a premium

See their website.

Another thought is in using a TRC-1 or TRC-2. I use the latter (have re-configured it a number of times; it’s what my big truck passenger seat radio rig is mounted). The former I gave my son for a CB system I gave him 6-7/years back.


The ability to disconnect and store the entirety of the radio rig for travel is not to be dismissed.

TRC-1 circa 2017.

TRC-2 (x2 units) circa 2021

POWERWERX is a good supplier.

I’ve bought a pretty big handful of these over time:

IMG_8452.jpeg

In my pickup the 6-AWG comes into cabin and terminates on HVAC unit with this. Distribution is available for more than just the CB. I use 10-AWG from here to a 4005 RigRunner for radio, amp, and speaker power distribution.

For big truck with TRC-2 it’s where truck DC connects.

With my sons install the same as my pickup eas done except on console rear.

HRO has these.

The RV radio rig w/SS30 inside a TRC and with PD75 can quickly be used 120V/12V.

Dog bed can go on top for when you want several radios to operate portable (not just mobile).

Run an extension cord for SS30 from motel room or genset. Etc.

On the SS30 power supplies make sure to check the tiny switch on the back. You can switch it from 220 to 110v and both of mine came set to 220v. They will run if you plug them into a 110v outlet but you won’t get full power out of it. So make sure to check!
