Re: AM Tuning Unit Design Software

I don't know why it took me this long to think about it, but how about loading Win7 or something older in a virtual machine using VirtualBox? I do that when I need software that doesn't run natively under Win10.

Re: Tomato Soup Incident

I was meaning to share this as it was told by a technical scientist I'm acquainted with: A user had apparent spilled some portion of a cup of coffee into a laptop they had been working on. The scientist picked it up and started walking to their lab hurriedly due to the spill. Unbeknownst to him one ...

Re: Tomato Soup Incident

I wonder if the soup is/was less toxic to the PC board than the incident I heard, which was when a jock dumped a large orange juice into a PR&E BMX console. Took out the entire backplane and then some. Luckily it wasn't at any of my stations.

Re: Monitoring, Day Sequerra Board Repair

Mind you, this comes from someone who's never really dealt with the HD side of things, but I'm curious just what is considered 100% modulation for the digital audio stream. I've been discussing with colleagues about the different references in luFS (loudness units full scale). Since I've never studi...

Re: Monitoring, Day Sequerra Board Repair

I had a similar experience with mine. It came back and the high level RF inputs no longer worked. Performance was tepid at best and the bargraph LEDs burned out, related to they receiving a batch of bad driver chips which would send spikes and burn the LEDs out. I'd buy an Inovonics or Belar HD moni...

Re: Realistic Service Manual Request

I looked in my archives and I only have a manual for the STA7 if you think that might be of some help.

Re: Realistic Service Manual Request

Did you try googling using the Rat Shack part number for the unit itself? Many times I stumble across service manuals using that method instead of the model name.

Re: Audio Bandwidth of an AM Broadcast Station

I remember how pleased I was when I engineered a pre-NRSC two tower AM directional daytimer using the Kahn AM Stereo system. Ages before I started engineering there the ops manager gave me one of the Sony SRF-A! AM Stereo Walkman© radios. When I first heard the station I swore I must have been liste...

Re: Simian or Station Playlist?

I'd be interested if that helps, Mark. I'm now intrigued to see if I can duplicate your situation on my system as I've never seen that occur.

Re: Simian or Station Playlist?

I have had StationPlaylist crash hard five times in the last three weeks. Not happy. What version? Are you subscribed to the StationPlaylist support list on Yahoo! Groups? Many times users come up with suggestions that solve issues. Ross has been excellent in support, but you need to factor in the ...

Re: RadioWorld Magazine

My original write-ups of StationPlaylist automation from 2007 and my product review of the Arrakis ARC-10 from 2008 is back, but I noticed with older content they removed my name as author from the article. My author's page only shows newer content of two guest commentaries and a recent product revi...

The site doesn't seem to be accessible at all now with IE8, either http or https. Luckily Firefox got me in but it lost the saved login info.

It's likely the security certs are too old at this point to work, as IE8 has been deprecated by Microsoft for ages.
