After missing it for several years, I managed to attend the Dayton Hamvention this year. This is the largest amateur radio event in the world, so definitely an event to attend if you are into ham radio. I had some concern about going the first year in the new Xenia location, but frankly I was never a fan of Hara Arena so I figured I’d give it a try. I met up with best budd Denny (KB9DPF) in Fort Wayne and we drove down Friday night, attending the event on Saturday and Sunday.

The short story is that we had a blast and the new location is an improvement over Hara (which is, of course, an easy compare).

We went early on Saturday morning, arriving at the fairgrounds around 8 AM (for a 9 AM start time). No traffic issues, easy access to parking. On Sunday we left a little later, arrived at 8:30 AM, again no traffic issues. (I suspect the traffic problems we’ve heard about were associated with arriving from the west, coming from Dayton. Also, that problem seemed to be mostly on Friday morning.)

Positives:

• Most of the buildings were in good shape [insert disparaging comment about Hara].
• Most of the buildings are not air conditioned but it seemed to be comfortable enough.
• The usual vendors were there…I couldn’t think of any didn’t show.
• The food selection was very good…basically “county fair style” vendors. For example, I had Louisiana style chicken, red beans and rice for lunch on Saturday.
• The forum rooms were pretty decent, as in large and convenient  [insert disparaging comment about Hara]
• I attended a few forums (all good): contesting, AMSAT, NPOTA
• Parking was convenient and no charge.

Negatives:

• The flea market was a muddy mess, so we skipped that completely. Those that went out there came back with shoes covered with mud. (I saw one guy that came prepared with 18-inch high rubber boots. Smart move.) I’ve seen lots of comments on the web about “well, you can’t control the weather so you just have to deal with the mud.” Yes, you can’t control the weather but even Hara had a paved parking lot for the flea market. Read: no mud.
• All of the food vendors were outside and there was little to no sheltered seating. If the rain had hit around lunch time, I am not sure where people would have eaten.

All in all, not too bad.

I’m sure they’ll be getting lots of feedback and will be working on the problem areas. I think you have to accept the fact that on a weekend in May in Ohio, you will get some rain. So something has to be done about the flea market, else its mud city most years.

Seriously, I think the Dayton Amateur Radio Association (DARA) pulled off a minor miracle getting Hamvention moved to a new location without a major problem. They had a well-oiled machine that knew how to make it happen at Hara but everything had to be reworked this year.

People often ask “well, why do they even hold such a major event in Dayton?”
The answer: because that’s where DARA is.

Mark, VA7MM, has been testing out his newly-acquired MFJ-1026 Noise Canceller and has provided several videos of the noise canceller in action.


Like so many other hams, Mark's suburban location has seen a gradually rising noise floor and the noise heard in this video is from an off-site location within his local neighbourhood, located about 400m away.

The noise canceller requires a separate 'noise antenna' in order to cancel any noise on the main receiving antenna and for all of the tests shown below, Mark's noise antenna was a Cushcraft R-7 vertical while using an Icom IC-7600 transceiver for listening.

Test 1 shows the noise canceller being used while listening to a broadcast station on 6.0 MHz:


Test 2 shows the canceller's effect on raw noise while viewing in Spectran:


Test 3 shows the canceller's effect on a 40m CW signal:


Test 4 shows the effect of just the IC-7600's noise blanker on the offending noise:


Mark's comments:


With proper tuning and set up, it looks like the MFJ-1026 can make a worthwhile improvement in unwanted noise reduction.  Mark will also be testing and comparing a Timewave ANC-4 Noise Canceller with the MFJ and any videos received will be published here.

With Hamvention already on top of us, I figured I’d throw my two cents worth into the mix with everybody else’s. In this episode of the Everything Ham Radio Podcast, we talk about some of the interesting things that are going to be going on at this years Hamvention at it’s new location in Xenia, OH.

DARA teamed up with The Miami Valley Mesh Alliance (MVMA) to setup a Mesh network on channel -2 at 10 MHz bandwidth.  The SSID is AREDN-10-v3.

We talk about all of my fellow podcasters/youtubers that are there and what they have going on and where they are at.

Lastly, we discussed some of the interesting forum topics that are going on during the weekend. To listen to the episode as well as check out all the links and further information on the topic, check out the show notes at:
