My Linksys WRT54G wireless router produced the usual birdies at 14030,
21052, 18090 +/- 60 kc among others.
A DC supply was tried and router speeds were toggled. No change.
FT240-77 toroids put on CAT5e cables. FT140-43s on the wall warts.
Cables dressed. Rig computer remains wired. Second computer switched
to wireless. Almost all birdies gone except when the router CAT5e
cable is connected to the second machine. Then some birdies returned.
CAT6 cables not tried. Difficult to replace on long runs but possible
last resort. All radio equipment is on a separate AC circuit from the
computer and internet gear.
I wanted the second computer to remain wired. The D-Link DIR-655
router was available. It's up and running. No birdies found so far.
Except some very weak ones. Power cycling eliminated local gear as the
source. The remaining birdies are antenna orientation dependent. I
suspect other routers in the neighborhood. Fortunately these birdies
are very weak.
Thanks to all who offered advice and suggestions:
G4ZFQ, PA5KT, NF4L (reported success with a D-Link 615), N4ZR, N9WQ,
W4BSG, KA5M (reported success with a Linksys WRT150N), WB4BYQ, NR1R,
K4FX, VE7HJ, KJ9C (reported success with a D-Link DIR-655), NØNB
(reported success with a Linksys WRT55AG), W4LDE, WS7I, N7UA and
anyone else I missed!
