Two assumptions that may not hold even in urban areas. Many cable / satellite subscribers are "cutting the cord" and going to over-the-air reception (I use that as a backup strategy when - not if - C*cast goes down), and because of the FCC's ill-regarded "repacking" scheme where UHF TV channels above 37 are being "re purposed" for the "broadband" industries' voracious need for spectrum, some urban TV stations are going back to their pre-UHF channels. With that said - I still use the "good old" external low-pass filter on my K2, rather than have it gather dust in the garage. Better be safe than sorry. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
