I think you are missing the main point here. Every teenager in the US has a smartphone. That smartphone can be turned into an ARDF receiver with the correct helper hardware. It’s even possible to do software defined radio using a front end that provides an I/Q signal. I think I know someone who made some software that can do that.

The purpose is not using the smartphone as some AI equipped automatic navigation device turns the user into a voice navigated zombie that just walks to the fox. After all in the real world that won’t help.

However the smartphone is a platform that every young person in the US already has in their possession. Just think if there was a low cost mass produced circuit board that would turn that phone into an ARDF receiver development platform with a graphic display. Maybe that could attract the digital savvy youth into the sport.

They are our future. Time Is marching on. Do we grow are just fade into the past?

I have seen this first hand at the hamfest tech presentations.  Traditional t-hunting  does not attract youth. I think part of the problem is the lack of access to low cost equipment problem. Just look at the cost of your receiver how many youth has a budget that can buy one? 

Another case in point. The software defined radio forums always have full  packed rooms. Adriano talks have full packed rooms. Why? Because they have low cost hardware platforms.

Botton line we need a very low cost easy to reproduce device ( for both receivers and transmitters) that enables youth to tray ARDF and radio direction finding in what ever format the hosted event may be. A cell phone or Pad is a wonderful platform to enable the realization of a low cost device that does not need an RF lab to align it. Just need some simple helper hardware to turn it into an experimental radio platform.

Do we continue doing the same with no growth?  Or do we change our path and come up with a low cost platform and attract new folks (that allows experimenting) and maybe will start to see new host venues for national championships? 

For example I think CW on two meters is the way to go 
1.it’s simple
2. Transmitters are easy to build and low cost. My practice transmitter uses a clock management chip and runs on a 9 volt battery for all day. 

Field testing this year showed that that mode works using the receiver development platform. We already use CW on 80. Let’s come up with something that can make  region 2 grow.

Moving by straight line without looking at the map is not an option, if you have an obstacle on the way - for example lake - by following guided line you will hit lake shore and will not find TX. So orienteering skills are required anyway.
