Hello Folks!

Last week i had a little bit of time to made some testing with speakers.
And a word before, here i can only describe my own (and subjective) impressions of sound.

The candidates.

Right side from above:
- conventional 28mm speaker with PP-membrane in Soundtraxx baffle kit
- 28 x 28mm High Bass 2W speaker with metal membrane
- 30 x 40mm speaker witn conventional membrane
All have an impedance of 8 Ohm

In the middle one of those astoning tiny sugar cubes Reinhard told me of.

Left side from above; alle were sugar cubes of the Knowles Dumbo 1W; 8 Ohm type, but in different enclosures from Zimo:
- 13 x 18 x 13mm
- 40 x 20 x 9mm
- 40 x 22 x 9mm; two Dumbos wired in serial; 16 Ohm
- 50 x 15 x 14mm; in effect intended for G-Scale; 16 Ohm

Alle speakers were equipped with wires and plugs, so that a quick change of the speakers is possible. The speakers without baffles or boxes got a special "hand" created baffle.




The stage.

Decoder tester from Zimo, here for all tests a Soundtraxx Econami ECO-100 Steam sound decoder was plugged to get equal preconditions. The sound volume was turned down to low volume and the adjustments were for all tests the same.
It is not my intention to make loud noise or simply a certain level of noise, but to get a certain quality of sound without a tympanum (eardrum) perforation. :hey:
The stage is set, the candidates are prepared and in near future i will narrate my impressions.

Cheers Lutz

Retired Engineer, Maurice Lewman, to Speak

Maurice (pronounced Morris) Lewman will be the speaker at the Society Meeting on July 25th at 7pm. He is a retired railroader who started his railroad career in Markleville in 1947 as a Section Gang worker until August of 1950.

In 1950 he started firing on steam engines and then moved into the Engineer duties. He transferred to diesels and stayed there as an engineer as he worked his way on the Michigan Division From Louisville to Benton Harbor until 1981.

From 1981 to 1992 Maurice worked the Big Four Bee Line Main. He has worked for the New York Central, Penn Central and then Conrail retiring before the railroad became CSX.

Maurice said, "I had the pleasure of working with C. C. Staley and Ron Buser many times." Buser contributed the Control Board from Gridley tower to us, and Maurice donated the 1/4 scale mock up of the Baker Valve Gear on a Steam Locomotive.

The Madison County Historical Society is at 11W 11th Street in Anderson Indiana. That is the double door entry.

If you are near to Indiana, come out and enjoy the talk by Maurice.

I came across a picture of this gp40 a few years ago and thought it would make an interesting model. It's the definition of rent-a-wreck with 3 different variations of rr schemes and donor parts. It's the only picture I've seen of it and I'm not totally sure who owns it. I've searched on rr picture archive for WC 3008, WC 3015, BN 3008 and VMV 3008 and nothing came up. It's confusing because the number board has 3008 but the rear hood dons a WC 3015 and the VMV across the old BN logo doesn't really stand out. I think if I try to replicate it the number boards and hood will have the same number for the sake of simplifying it, that or some sort of fantasy lease company. If I go that route I figure a large majority of lease company reporting marks end with an X and I'm a fan of punk music I thought for $h!t$ and giggles the reporting marks could be NOFX and go with a similar decrepit scheme. Either way the model will be a gp38-2 just because I have a seaboard system 38-2 I can use. If anyone has info on this engine I'd definitely like to hear about it and get some feedback and ideas.

Conrail's WPMA-40 works the area around the piers.

I was working on a Csx caboose a few year ago and is in the scratchbuilding section. Long story short I bought another one but I decided to let the pros handle this one, here's a progress shot from BradleyDCC. He's doing the sound install and weathering for me and he's done way more than I expected.

I'm looking for an HO scale p2k gp38-2 88" low nose and cab, preferably Burlington Northern green & black scheme but any 88" nose without the headlight would do.
