[Elecraft] K4D for bargain price on eBay

[Edward Mccann]


Not too worry fellas, the posting notes there are only ten kits available. That means the fools errand will have been run by at least ten gullible hams before the stock is exhausted.  

The vendor will be up $1500 less whatever he drew from his junk box to complete the order.

The Greater Fool Theory meets Maxwell.

If that's what you're looking at, it's an "RFI Kit" for a K4, I don't think it includes the K4 itself! {'-)
