Prior to Dayton I built another 2 meter portapeater (147.585 in/144.930 out) & packed in in my suitcase (I flew this year). Unfortunately I forgot to pack the crossband diplexer (for the 440 remote link to the Miamisburg repeater) &, more importantly, the correct interface cable between the MVP repeater radio & MP100 controller!

As you can see here, the control cable issue was fixed (take a close look at the connector on the back of the MVP). I found a vendor selling female Molex pins Thursday afternoon, which I used to build an interface "haywire" set Thursday night.

Thanks to John KA3LAO who graciously provided a crossband duplexer, the linkup to WB6VSU was complete. The Miamisburg repeater heard much better than it did 2 years ago, as we later discovered that we could access it all over Hara; the problem was hearing it through all the IMD.
The wood thingy on the dashboard is my GPS holder. I used it along with MS Streets & Trips to get around. Unfortunately the DC/DC converter for the laptop died right after the hamvention, so I was "driving blind" until I picked up an AC inverter in Indy a couple of days later. Not fun.

Dayton Hamvention attendees pouring into the parking lot across the street from Hara. I always opt for this lot even @ $10/day because of the proximity needed for the portapeater to adequately cover the grounds.

My car is at the far left. The next day I arrived earlier so I could park closer to the fence & get even more coupling into the swap area. I discovered a nearby noise source that hit the 147.40 to 147.60 MHz range, severely desensing the MVP receiver. I'd have been better off using 147.75 for the input like I did in '05 (147.585 is the standard portable repeater input in Southern California, & Ohio doesn't have any allocation for portable repeaters so I just went with our bandplan assignment). Oh well, next time...

WA5KUB's streaming video. If you can't make it to Dayton, you can watch & listen in near-real-time at wa5kub.com. We tested the webcam's delay; it was 10 seconds. Tom said that usually it's 30 seconds.

The Dayton Hamvention is a big deal in the area. With ~20,000 attendees, it gets serious news coverage.

Sadly, the "Repeater Builder" crew couldn't make it this year; their spaces went unoccupied.

I think I've seen this HT/antenna every year I've been to Dayton.

The broken asphalt's starting to become a real problem at Hara. I stumbled on loose asphalt stones a couple of times.

Lots of free stuff at Dayton on Sunday afternoon.

The grand prize is sitting on the left end of the back table (middle of picture): a complete ICOM DStar repeater system. MSRP: $8000. No I didn't win it, or anyting else for that matter  :(

OK, off to the National Air Force Museum, just down the road. I managed to walk through all the hangars in half a day, but this is really an all-day activity.

Yup, that's a B2 stealth bomber. The thing's so wide I had a hard time getting it all in one picture.

B2's cockpit. This picture sure makes it look like some alien spacecraft. In fact, the whole plane looks alien in person.

Not sure what this is; looks like a "stealth missile".

My visit to the Toyota assembly plant in Georgetown, KY. Unfortunately this is all you get to see here because they don't allow cameras on the tour. Guess they're really worried about corporate espionage. Too bad - the welding robots would've made for excellent pictures.

On the way back to the airport in Chicago, I had most of the day to kill & I was passing through Indianapolis, so I got off the interstate & drove down to the speedway. The Indy 500 was only 4 days away, so all the vendors were already setting up. What this one sold I'm not quite sure...

I think that's the track just behind the railing.

Traffic control around the speedway was already in place.

Another stop at Purdue University in West Lafayette, IN; this is where the "Boilermakers" play. My GPS wouldn't work here; I concluded that there's TI (terrestrial interference) being generated in the area. I had to find my way out without GPS data to the computer.
