Since I haven't seen this posted yet: Use a VLF convertor to up-convert the sub-carriers to 4 Mhz. Then tune 4 to 4.1 with your HF rcvr ( my R71A has FM ). Even using AM with 'slope-detection' should allow you to 'investigate'. If you find something really worthwhile, then worry about building something. Some receivers will pass enough of the sub-carriers right out the speaker jack and some may require you to connect to the discriminator. ------------------------------------------------------------------------- lrk@k5qwb.lonestar.org lrk@k5qwb.UUCP 73, utacfd.utarl.edu!letni!rwsys!kf5iw!k5qwb!lrk Lyn Kennedy K5QWB @ N5LDD.#NTX.TX.US.NA P.O.
