74HC4052 ok on the 200 ohms. I think I already noticed that and downloaded the data sheet. I am ordering allot of ICs to have around and I will try this one then. An Cecil says some are good to 70 Mhz and thats real fine for HF uses. 6 meters even. Given a 74 to 78 MHz DDS or VFO we coiuld get up into 2 meters. Using a 70 MH i.f. or something. Oh WJIE shortwave here in Kentucky is going DRM soon! So we will keep and eye on them. They got a deal on transmitters and brought them here. The FCC finally let loose digital broadcasting here and so its launched. All of that argument over what sort of standards they wanted here. Mainly it was over patent technolgies in the method of DAB. Who got to control the market was the hold up. I think DRM won something here. Anyways I am going to use the bitlaral swithces and the Gilbert Cells. I don;t know what wil happen with the Gilbert cells but they seem liely for transmit and receive.
