Gordon's Hobbies...

Hi, I'm Gordon, chief engineer for, and totalitarian dictator of, Radio Free Burning Man. I created this page to show other projects I work on and play with besides RFBM.

35mm Projectors

Here are some images of me goofing around with 35mm film projection equipment.

Some of my equipment consists of Simplex E-7 projectors, RCA Photophone MI-9030 soundheads, and a single home-made folding pedistal system.

I've since replaced the Dolby CP50 with a CP200. The CP200 has one Accessory unit and an SRA-5 analog SR adaptor. There is an MPU-1 in the kit, but little chance of ever running magnetic soundtracks or even connecting the audio.

The LCR screen channels are JBL EON-15 powered PA speakers. There is, as yet, no screen. Despite the limited conditions I've run this equipment in, I am impressed by the performance on all three basic optical sound formats (academy mono, A-type w/ surround, and SR-encoded).

The projection light source is now an ORC M1000 lamphouse with a 700-watt LTI (now Philips) xenon lamp which I run at the reccomended 37-amps. There some optical bugs to work out, most of which are related to having never run it with more than a twelve-foot throw.

 


Amateur radio

A 1976 Yaesu FT101E serves as my access to the HF portion of the hobby.
I've reconditioned this Cushcraft R7000 antenna. After much work, SWR is below 1.3:1 on most of the bands. I've worked 40, 20 and 10 with this one.

Restoration:
