Jose CO6EC has been digging up 30 year-old Islander schematics for us. Thanks Jose. This one shows a VFO for the Islander. Note that it runs on 80 meters, but they select the second harmonic at 40 meters. This was a smart move that surely helped with VFO frequency stability. <\/b><\/div>\n<\/p>\n
<\/a><\/div>\n
Jose sent this printed circuit board pattern for the VFO. Obviously they were making many of these rigs. <\/b><\/div>\n
<\/div>\n
<\/a><\/div>\n
Here is the power supply. Jose reports that the transformer came out of a Soviet Krim 218 TV set. As a kid, I also pulled a transformer out of an old TV — I did it to build a power supply for a Heath HW-32A. <\/b><\/div>\n
<\/div>\n
<\/a><\/div>\n
Here is another version of the Islander. Click on the image for a better view. Jose reports that this version was circulating during the time <\/b>Islanders were being built. He says this diagram many have been done by Arnie Coro CO2KK (SK), and may have been circulated on the internet. <\/b><\/div>\n
<\/div>\n
<\/a><\/div>\n
Here’s the first schematic that Jose sent. Again, click on the image for a better view. <\/b><\/div>\n

<\/b><\/div>\n

<\/b><\/div>\n
I will continue to gather information on the Islander and the Jaguey. If you have any info please send it to me. <\/b><\/div>\n

<\/b><\/div>\n
Here are some earlier posts on these rigs: <\/b><\/div>\n
