[Flexradio] Ugly mixing products on 20M

[Mike Rice]

This problem is completely fixed--traced to a bad NIC (ethernet) card in one of about 100 computers on site.  Everything is working much better now ;-))  Thanks to every one who had sugestions.

        /Network wireless router in the house?  "smart" battery charger in the garage?  I had to chase both of those.  Description looks more like my WRT54G....

Mike I am getting those spurs at the exact spacing you mentioned. When I put thedisplay in spectrum mode to magnify an individual spur, I see that each spur iscomprised of 3 peaks. The second peak about 450Hz away from the first with theother
 three 300Hz apart. Disconnecting the antenna almost eliminates them too.JimK5HY----------------------------------------> From: nmskies at nmskies.com> To: FlexRadio at flex-radio.biz> Date: Wed, 4 Feb 2009 15:16:45 -0700> Subject: [Flexradio] Ugly mixing products on 20M>> On my Flex 5000A I'm getting some very strong spurs or mixing productsof some kind from 13.297 MHz through 15.804 MHz> at exactly 61.040 KHz intervals.
