Hmmm, I’ll bet that is how it is getting by. Thanks. 465 is right in the middle of that.

That does seem odd....what power level does it put out? Jaime Solorza On Sat, Jun 30, 2018, 11:44 AM <[email protected]> wrote: I have a horizontal directional drill. The drill bit transmitter (sonde) talk to a receiver. They are pretty low frequencies, like 8 KHz or something like that. Then the locator sends data to a remote indicator on the machine. One of the antennas (the one on the remote indicator) was messed up and one of my guys just put a random length of wire on it. Range is not good. I told him I would figure this out and make a better antenna. That is the easy part, I just swept the other good antenna and noted it resonates at 479 MHz. Will make a sleeved dipole for it. But now I am wonder if I ought to be licensing this thing? I expected it to be in the 300 Mhz unlicensed band (316 or whatever it is). Never thought it might be illegal until this morning. FCC band plan shows the following for that frequency: Public Mobile (22) Broadcast Radio (TV)(73) LPTV, TV Translator/Booster (74G) Low Power Auxiliary (74H) Private Land Mobile (90) That is all licensed stuff. -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com ---------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- Forrest Christian CEO, PacketFlux Technologies, Inc.
