This was my #1 site. I wish that whatever the problem is, it would be fixed?..

Always a great hamfest. Lot of stuff. I'll be there even with free stuff.

Today only three registered users accessed the board, but 378 total users were logged.  If bots are scraping the forum for data, and that is the root cause of the server error 500 normally encountered when the bot usage is extreme, it seems there might be a very easy fix that the admin might apply.

Simply alter the access capability such that anyone who is not logged in with a valid account can only access the login menu.  Without entering a valid username and password, no other access would be allowed, effectively locking the bots out of the forum.  Currently the forum allows unlimited access to EVERYONE, and a valid login is needed only to post replies or start new threads.  Even QRZ.com requires a valid login in order to obtain any valid information about users, etc.   Access without a login and password is extremely limited, as it should be.

That change would be a minor inconvenience for regular users.  The user database could be filtered (one time task) such that only valid calls, matched against the FCC license database, would be approved for access.  Separately, SWL and CB users could be granted access on an exception basis, but if nothing on the forum is accessible without a valid login, the bots would just "go away".   This would mean folks could not browse without a login, but this would be a minor compromise in order to keep the forum alive for bona-fide users.

You've practically killed your own site by continuing to let it be nearly impossible to access. What's the problem? Somebody on another site you were relegated to very low priority on their rented server space, whatever that means. Or maybe you just plain don't care. All I know is there's no point in even coming here. If I were to make a post asking a question, or answering one, it could be months and months or a year, 2 years before anybody even sees it. Either get busy fixing your access problems or shut it down. What you've got going on now is one big fat nothing. Ban me if you don't like what I'm saying. Who cares?

Carrier on 7291 khz!

Please do not use 7290 khz for AM.....
Last night I heard on a webreceiver in Usa a station calling cq.
Not possible to hear him on my own receiver....

For example 7285 and 7295 are better frequenties....

AG5UM, yes this is a cool, but slightly frustrating project.
There is some great information on the sites that that you have linked. Here in Brisbane Queensland, we have an AM net on 40 or 80 meters 4 times per week.  Numbers vary, but there are 2 stations using 18S-4 radios, with another 2 in storage at various QTH's, plus mine.  I think the market is saturated!

Opcom, thank you for your information.
I am leaning toward the motor having an issue with the brushes, but I really hope it is dirty relay contacts.  (This radio loves relays!).
I was lucky enough to get an original manual with the radio.
All 18S-4 radios in town have had the dynamotor removed and run on separate power supplies.
Lucky for me the cradle was included so I didn't have issues with connectors, other than a clean.  The secret is to not force them, but they need to be firmly seated.

Thanks for the replies.

There is a diagram for each of the setups in my manual:
