Is there a specific groups.io site for Oak Hills Research transceivers?

A friend of mine has an OHR Spirit transceiver, and he is trying to find information about it, manual, and schematic.

Thank you.

Dave K8WPE?


 

I have the manual scanned in for the 20m version that I built
back in the day.? File size is 1.7MB.

Gang,

Doug DeMaw, W1FB, started Oak Hills Research way back in time.
Dick Witzke, KE8KL-W7DKU-K7NL <sk>, bought the company and produced
???????????? a large number of kits that we all probably have one of or more.
???????????? The most famous being the WM-1 and WM-2 QRP wattmeter.
Then Marshall M. in CO (missing info on my part) did some of the kits afterwards
???????????? until his passing.

I think I have all the manuals from all the kits I ever built scanned in.
I will start putting them on archive.org for preservation as long as possible.
After today, if anyone needs a manual, search there first.? If you have manuals
that I don't have, then you should put them there.? There is no reason for the
history to be lost.? Too much has already.? IMHO.

I'll post list when I'm done.

Chuck,

What parameters should I use for Oak Hills Research manuals, schematics, etc?

Thank you for doing this favor for us.

Search for OHR, Oak Hills Research and QRP should do it.
Got the Spirit I manual uploaded.? Rest of them coming
as we speak.? For specific rigs you might try the
name of the rig.? I'm trying to get all the meta words
in the description and I'll edit what I forget from time
to time as I catch it.

My wife has a fractured bone in her foot, so I'm aperiodic
on getting things done for the next six weeks or so.? I'm
Uber Drive etc, so if I seem incompetent, it's because I
am.

thanks,

Chuck,

Thank you so much for the OHR manuals. Having them available is a real find.

Hope your wife¡¯s foot heals quickly¡­.. drive safe. You have a precious package. I am getting older and my wife is doing more driving. Then I can sit and enjoy the ride or watch videos on my phone¡­ha!

Also while you were downloading to Google I found a very old series of emails about the OHR Spirit by a British ham. I looked him up and within a few hours he responded with the manual and the schematic for my friend in Florida. We are so blessed. Yes, the web has your life hidden somewhere but when used for good it is a miracle.

Again, thanks so much.

I have an OHR 500, the DDS that goes with it, and a WM-1 that I have picked up along the way.? I will go through my manuals and scan/upload any that aren't on archive. org.? Thanks Chuck!

Thanks.? I have the manuals, but it would be nice to get them
from some one else to make sure they match.

It is appreciated.? Thanks for the help.

Hi
?
I uploaded some OHR Qrp Manuals in Files Section. Still I do not have any:)

Regards and 73s de TA0G

Hakan,
?
Very respectfully, there are already copies of the four OHR manuals you uploaded. They are in the "OHR" sub-directory. You might want to inspect and -- if duplicates -- remove yours as space is somewhat limited. If they are NOT duplicates, then move the unique manual(s) into the sub-directory so as to keep them in one place and easier to locate.
?
Again, meant politely.?
?
Thank you for your contribution.
