Bob, I'm in need of a replacement receiver. The transmitter I have is a Hitec Laser 6 FM on 75.730 (CH77). The now 'broken' receiver that came with the radio is a Hitec HFD-08RO. On the receiver it says Dual Conversion, Ultra Narrow band, Negative shift for 75MHz. For the Subtech receiver, its says not compatible with dual conversion crystals so I'm also going to need to buy a crystal as well. Short crystals appear to be available on eBay or Tower Hobbies. Are there any other issues I may have?
