I don't know how much interest there is here in old radio broadcast equipment, but I have been collecting it for the last couple of decades. Along the way, I have come across a lot of information (and a lot of myths) regarding studio broadcast boards. Since my interest is mainly--though not exclusively--RCA, that's what I have collected the most information on. If anyone is interested, I have posted a brief rundown of the RCA 76 series of consoles on my web page at http://www.kwd-radio.com. Just click on the "Consoles" link on the left. The information is pretty condensed, but it's the sort of stuff I wish I had been able to dig up way back when...

Two different people have told me the link doesn't work but I can't replicate the problem. Try copy/pasting the URL and see if that works.

Just tried it, and it works fine from here. Your ISP could be having some routing problems.

Odd. Very odd.

Hard to imagine why Firefox would give and error, and sure enough mine does!
Perhaps post a link that is deeper in the website??
Maybe that will work.

Strange.

Great site -- so much to read and see. Warms the heart of an ex-RCA (video) engineer of 31 years with the Corporation.

Thanks for the compliments. I started the site years ago, partly as a way to gain a better understanding of html and website design. From what I've been able to find, some of the internal headers in my code just don't agree with some browsers (most notably Firefox, apparently). Much of it is still a work in progress. I think it might be time to start working on some code modernization.

Norton, in their "safe search" category, your site also comes up as untested. I use "safe search" with Firefox. If you Google kwd-radio with Firefox, you site comes up with KWD Radio and a [shaded box with a ?] If you as the site owner click on the shaded box you can have them "test" your site. Maybe there's a connection with Firefox.

Maybe not well known, but a number of web site hosting providers have tighten up their security protocols over the last several months. Many of the older versions (and some not so old) versions of various browsers are not longer (or soon will no longer) be supported. I go through this with customers at least once a day.

I just tried your site from the link Pete posted.  I am using Win 10 with Microsoft Edge browser and your site was a fast load.  I like that.

The link worked fine this morning as it does now. IE/Win7 pro.

Interesting site. Good job. One issue though: the 'General Radio modulation monitor' shown in Other Broadcast equipment looks more like the small RCA console...

Still doesn't work with Firefox V 41.0.1.  Always worked for my IE 11, Win 7 Pro.

 Nice site

Bill,

I am glad to see that the wonderful photo of WMRN's transmitter room my father worked at in 1941 is getting viewed by the world.

Working on chrome both using lte connection and wifi.

Tested on Chrome for Ubuntu on my server,  works.

Tested on Firefox,  did NOT work.   HOWEVER,  when I copy a link from chrome and paste into Firefox (ie,  copied the url for his ham link) and it works.

Points to a Firefox issue....   Probably with his home or index page naming convention.

The following link DOES work in firefox:

D'oh! You are correct. When I added that page, I used the RCA BN-2A console photo as a placeholder and forgot to change it. Thanks.

Hi Tom,

I'm curious - How do you suppose they controlled the transmitter blower noise from coming over the mic?  With no glass barrier, you would think it would be a problem ?? Then there's the problem of heat during  summer without air conditioning in the '40's...

Use an "AM Courtesy Filter" to limit transmit audio bandwidth  +-4.5 KHz,  +-6.0 KHz or  +-8.0 KHz when needed.

Many stations used remote studios over landlines but still maintained a working, bare bones studio at the transmitter site in the event of problems. Wonder if that was the situation here?

Nice site. The link worked for me. Having started working in radio in the seventies spent lots of time removing and replacing vacuum tube consoles, monitoring and processing equipment and at that time no one had any love for that stuff.  Maybe in the forties and fifties when that stuff was new it was good but by the seventies it was all old, unreliable and preformed nowhere near as well as the cheapest solid state equipment. Like you I am amazed to see the price this stuff sells for today. Know of several RCA and Gates tube consoles that I gave away as late as the nineties and at that time very few wanted them and items like RCA program monitors, line amplifiers and the like often went straight to the trash. Back in the eighties I would always sell at the old Timonium Ham fest and drag a bunch of the RCA and Gates junk and never sold any of it. Things like patch fields, M-67 mixers and solid state Volumax and other solid state processing would sell at ham fest but not the old tube junk, maybe thatís why itís worth so much today?

Very cool picture of Joe (IBX).
Is it old before the equipment went into the basement/garage/remote shack or more recent and stuff is invading the kitchen?
Is there a T368 in the bathroom?
