[TenTec] Orion II 8 Pin DIN

[Kirk]

It probably is true that Burghardt may have the DIN plug you are looking
for.  My personal experience with Burghardt is that they have horrible
customer service.  After my last experience with them, I'll not deal with
them again.  I have switched to and find Texas Tower not only has great
customer service but always has the part that I'm looking for.
Obviously, to each his own.

Happy New Year!

I was looking in the Mouser catalog last night and it appeared that the
8 pin plug in the catalog had the 270 degree angle but the center pin
was offset .070" towards that gap. Some one on a microwave reflector was
looking for the Kenwood plug. Another place I have bought such plugs has
been Hosfelt in Ohio. Very good prices but shipping is sometimes high. I
doubt they know the difference in the two plugs. Burghardt in South
Dakota is pretty good about keeping such plugs on hand at reasonable
prices. http://www.burghardt-amateur.com/Burghardt/HTML/main_frame.html

Some Kenwood rigs have a switch embedded in the 8 pin din chassis
connector to switch the VFO for external use when the plug is inserted
and its the external VFO socket. So they want the wider space for thee
switch actuator.

At Mouser,  their part number drawing for 17HR598 shows a 270 degree
with the center pin offset .028".

17HR618 pictures a bigger offset but doesn't dimension it and claims a
270 degree arc.

174-9281 implies a 270 degree arc and dimensions a .028" offset.

They don't have a drawing for 171-1080-EX but the catalog page shows 270
degree, but not the center pin offset.

171-0288 shows 270 degree but not the amount of the offset, though there
clearly is an offset.

Switchcraft 502-15GM8M isn't stocked but the drawing shows only three an
5 pin with no pin dimensions.

17HR808 is marked as obsolete. But the drawing implies 270 degrees and
it shows the .028" offset (which would be .07 cm).

171-1081 is also marked as obsolete. The drawing shows 270 degrees but
doesn't dimension the obvious pin offset. Its a right angle connector.

Have you talked to TenTec parts about the mating connector?
