As Doug pointed out, either a double or single conversion receiver will work with your transmitter… Also as he pointed out, the crystals are different for each…
Your Laser 4 is called double conversion because that is the type of receiver that came with it… Today, many single conversion receivers operate as well as the doubles… Some like the Berg are using a DSP routine to lock to your specific transmitter and reject the others… Seems to work, I have not been shot down for a long time using the single conversion Bergs…
Guess I will just have to spring for one of the 75Mhz ones and give it a try… In a sailboat senario, a glitch or shoot down is a far less critical thing than in an aircraft… I may need the chase boat but probably not a body bag to bring back the pieces…
