I added theTransroc microphone kit to "hear" what was going on inside the rocket.
It wasn't very impressive. You heard the hiss of the engine, some wind noise and the ejection charge.
Pretty much the same sounds you heard from the ground without the walkie talkie!

They were "Estes' Heathkits," so to speak. :-) A very simple (it has only six electronic components), one-transistor 27 MHz tone transmitter and a single-channel, three-transistor 27 MHz transmitter are covered in the 4th and 5th editions of G. Harry Stine's "Handbook of Model Rocketry." They can both be made using perfboard circuit boards (if desired, several firms offer custom PC [Printed Circuit] board making services). The one-transistor transmitter would make a good, simple tracking & locating beacon. |
