yeah i know that for hobby stores to keep stock of all frequencies they would probably nees another store just to keep them all in. but when you cannot get the cystals you want and ask to buy a new receiver to overcome that problem and be told sorry we dont stock them what the hell they sell kits but no r/x's [&:] its not like i am saying i need one on one freq only i asked for channels 19, 21, 29 and 31 but no low band rx or high band for that matter. well im happy now as i ended up just buying a new module and using the crystal out of my P51
