[NSRCA-discussion] Heathkits

[jeffghughes at comcast.net]

Heathkit is still in business selling electronic training stuff. I grew up in SW michigan where they are headquartered, so between my Dad, brother and I we built most of their stereo, electronic and TV stuff.

I'm still using a Heath ESV, one of the few that does single nicads. 

Though, I have not found much use for the timing light for a while -  <VBG>

Agree on missing the stores and the kits.  That was my introduction to Elec. Engineering and programming which has ended up putting a lot of food on my table over the past 20 years.

I used to live at the Heathkit store in Pittsburgh when I was a kid. Never 
used their RC stuff but I did build one of their robots. I miss their kits.
