Please consider this a newbie question. Am an SWL, not a HAM, and am considering an MFJ loop as the primary indoor SWL antenna, along with an active antenna as a less potent secondary, the two connected via an antenna switch. So lets say I read in a schedule that a certain frequency in the 49 meter band right now should have an interesting broadcast station on the air, so I set my receiver digital readout to that freq, then what's the procedure to tune the loop to that same exact frequency, having no transmiter? Thanks for any help! Tune it for maximum noise or signal on the frequency. You should hear the motor noise on your receiver as the capacitor turns. Then fine tune it back and forth. -- -------------------------------------- Diagnosed Type II Diabetes March 5 2001 Beating it with diet and exercise! 297/215/210 (to be revised lower) 58"/43"(!)/44" (already lower too!) -------------------------------------- Visit my HomePage at http://members.shaw.ca/finkirv/ Visit my very special website at http://members.shaw.ca/finkirv4/ Visit my CFSRS/CFIOG ONLINE OLDTIMERS website at http://members.shaw.ca/finkirv5/ -------------------- Irv Finkleman, Grampa/Ex-Navy/Old Fart/Ham Radio VE6BP Calgary, Alberta, Canada |

Hello
Tune it for maximum noise or signal on the frequency. You should hear the motor noise on your receiver as the capacitor turns. Then fine tune it back and forth. Right, just tune for max. noise or signal, please notice that some loop,s are very sharp and have a very small bandwidth. And if you can hear the motor turning the capacitor, then return the antenna to the manufacture and tell him to design his products properly. Regards Max |
