Hi Skipp, Thanks for the info. Hmmmm, seems to me I have a box of receivers around here that looked like Spectrum stuff, but was up in the 460Mhz range. That was years ago and I vaguely remember buying them for spare parts. Time to get the snow shovel out and dig down about 10-15 years in the pile. My miners helmet is around here somewhere.................
