. . . I'm rambling again.
I was listening to some 8444 and 4449 recordings on LP today, and the MP 100 definitely sound ed better than the C-34 using Dynavector cartridge. The MP 100 didn't load up and sound over modulated like the C-34 did. I will say the old Soundstream recordings don't match up to my recordings I use make with Telefunken mikes. My recordings do have tape hiss even with Dolby noise reduction. But thats analog. I use to go out and chase trains using Ampex 600-2 using a Trip lite inverter in the back of the van. Then I changed to an A-77 2 trk MK IV. Then a portable Nakamichi so I could place the mics right near the rail,. and finally A Professional Sony Cam corder with Dolby. With careful adjustment the Sony gave the best results and I could have picture, too and didn't need the Trip lite. Some where in there I changed to a small Diaphragm Audio Technica Stereo Mic. The sound was better, but the bass wasn't as impressive. When we traveled behind 8444 and 3985 in the sound car they would supply us with 120 volts AC to recharge our batteries or to power our recorders. By the time I got to ride behind 611 and 1218 I was using my Cam corder and all I had to worry about was keeping the batteries charged and the lens clean from soot and steam vapor. I have no remembrance of How loud a steam whistle under a passenger load dock shed can be when standing next to the drivers, but your entire body resonates when 8444 blows her low pitched steam whistle. I have tried to duplicate the sound and even the big discos couldn't come close. I will say 611 and 1218 were much superior mechanically in fit and finish to the UP engines in the 80's. I was in Portland two years ago as they were installing new flews in 4449 and they are doing the same thing now to 611. UP is restoring 4014 one of the largest Articulated steam locomotives ever for the 150 th anniversary of the golden spike next year. I plan on being there. I'll have to break out the Go Pro. Surely the Pros will be there to record the event in 4K
