List of mw radio stations in UK
@Jeff That's a useful link Jeff. It does seem to indicate there's no high power transmitters around 500 to 550, which renders radio interference an unlikely explanation, unless Wildy happens to live next door to one of the few low-power transmitters. Correct me if I'm wrong, but wouldn't the high margin on these tones just be consistent with the fact that they had been unavailable in the past, and the router hadn't got around to swapping them back - or for that matter, the router hadn't bothered to swap them back as it had nothing to gain, since it could easily maintain its connection speed without swapping? What do you think, Jeff?
@Wildy, in addition to Jeff's comments, do you hear any marked buzzes/crackles on the radio - perhaps intermittent - in the region I mentioned...? It's probably near the end of the dial (lower freq/upper wavelength) on the MW band?
BTW, RS is clearly incredibly useful but it's not very responsive in real-time. If you think there's an intermittent problem, I personally find the native Netgear HTML interface is often better as it reports the SNRM with a refresh rate that's configurable right down to 1 second. If you have access to something like a small laptop, or better still an Ipod Touch or the likes, you can either listen to a radio, and/or wander around the house switching things on/off, and see an almost instant change in SNRM when the problem strikes.
