I looked at this website several years ago, found things that were dead
wrong from and RFI perspective, and took them up with the author who
refused to accept my advice. I didn't bother to read further. There may
be some good stuff there, but I don't recommend the site.

Re: Going Mobile?

Yeah, just remember..........everything written and printed and found on
the web is not necessarily correct, nor accurate, and not of the current
methodology of doing things. I find that a lot of info borders on what
someone told their brother in law, that has a 3rd cousin who was a
neighbor of a ham some 20 years ago. Of course in that case........once
it is said it must be fact!

Re: Going Mobile?

In the late 1980s WB6FDR showed me his mobile station that had a Kenwood
rig with a small control head which he had mounted on the dash of his
Mercedes. The rest of the rig plus a KW amp all fit in the trunk.

I recall that one of the old W6SAI handbooks showed a mobile rig with an
amp that used water cooling.

Re: Going Mobile?

Yes, the water cooled antenna amplifier was a Dalmo Motor inverter and Jennings 2w300b tetrode amplifier I had one. I still have the amp and manuals.

Re: Going Mobile?

In reply to this post by Bob Nielsen-4

I recall a construction article a long time ago (mid 1960's) in GE Ham
News where W8DLD constructed a 1KW mobile linear using a pair of
Grounded Grid 814 tubes and developed the HV from a modified alternator
to bring the 3 phase AC out and run it to 3 transformers.

Of course, in those days, there were no computers in vehicles to be
concerned about, and there was plenty of room in the vehicle to mount
the exciter, usually under the center of the dashboard. Remember that
the Collins KM1 and KM2 were designed as mobile transceivers, and they
were much larger than the K3.

Re: Going Mobile?

I hate to think how much of that kilowatt got absorbed by the operator.

Re: Going Mobile?

A memory:
1955 I was at the Virginia Phone Net picnic at a farm. A guy pulls up in a Plymouth coupe with a huge plastic box on the roof with large coils and capacitors showing. Sticking out of it was a long vertical antenna.
He stepped out. He had a microphone harness on which had probably been from the Navy. He pushed a button on it and a huge whine erupted from the trunk. He then pointed a piece of wood near the vertical and drew a tremendous arc to it.
He opened the trunk and we saw several large dynamotors and many batteries. Yes, he had a 75M kilowatt AM rig. Pretty amazing.

LMAO! Wow!!! Can you say HIRTA? That is an awesome story.... My uncle
had lots of oddly funny/scary stories like that having "grown up" in the
air force (35+ years).

Thanks for making me think about the man in the #2 spot on my "Heroes List".

Then I noticed that the fire control radar on one of the F-86's nearby with the radome off was "looking" right at me. I moved several meters to one side and the dish followed me. I was being irradiated by the RF, raising my body temperature. I just moved further away. No one thought that was remarkable.
