That’s the front panel. Glenn’s kids and grand kids liked sitting on his lap while he played radio and putting stickers on it<\/b><\/span><\/div>\n

<\/span><\/div>\n
This is one of the best HB2HB contacts I’ve had. I was just getting ready to sign off on 40 meters when I heard someone calling me. It was KU4NO. I thought I’d just give the OM a quick report. Then he said, “My rig is homebrew too.” And wow, it is indeed! When he said this my first thought was that maybe this was a kit rig, but no, it turns out that this rig is the scratchyist of scratch-built rigs — true hardcore hardrock homebrew. <\/b><\/span><\/i><\/div>\n

<\/b><\/span><\/i><\/div>\n
I checked my log. I had worked Glenn once before, in December 2001. I was in the Azores. And he was using this same rig. Glenn told me that for all these years, this has been his ONLY rig. A friend gave him a modern commercial rig, but he prefers this one. I understand completely. <\/b><\/span><\/i><\/div>\n

<\/b><\/span><\/i><\/div>\n
At first, Glenn made me promise not to share the pictures with anyone. He seemed a bit embarrassed by his creation. I told him that SolderSmoke readers would appreciate his rig and see the value of it. I explained that we all have soldering iron scars on our fingers, and clothing that has been stained by ferric chloride. We LIKE ugly. It took some persuasion, but I got him to agree to let me share this with the group. <\/b><\/span><\/i><\/div>\n

<\/b><\/span><\/i><\/div>\n
Glenn reports it is based on a “5 band transceiver” circuit in the 1976 or 1977 handbook. (i don’t have one and can’t find it on-line — can anyone get us a copy of the schematic and article?)<\/b><\/span><\/i><\/div>\n

<\/b><\/span><\/i><\/div>\n
So I say THREE CHEERS for Glenn KU4NO and his homebrew 5 band transceiver. For me, the stickers are the most important feature of this rig. Please e-mail me your comments on Glenn’s rig – in an effort to let him know how much we appreciate and understand his effort, I will pass them on to him. I wish more hams would follow his example. <\/b><\/span><\/i><\/div>\n

Oh well I’m not too concerned about who sees it. <\/b><\/div>\n
I just wouldn’t want to cause anyone to follow my example. <\/b><\/div>\n
Maybe you could call it “a tornado goes through a junkyard.”<\/b><\/div>\n
Just kidding around …no restrictions…I’m sure it will be forgotten soon ….. but I will be innocent of any harm caused by it. <\/b><\/div>\n
Its the only rig I’ve ever owned when we contacted before it was with it. <\/b><\/div>\n

<\/b><\/div>\n
The inspiration article in the 76 or 77 handbook is worth a look. <\/b><\/div>\n
The VFO tuning cap and mount came from a CB “slider” one of my brother-in-laws gave me it seems to work well<\/b><\/div>\n
