qcx powers up, but no calibration tone
Just fired up QCX first time. Got to initial calibration menu but there is no tone. Something simple? How do you reset the controller program? I entered several values that were inappropriate. Thanks,

I don't know what you're on about, but if you have some problem with me, why don't you deal with it like a grownup and send me private mail explaining what's wrong.? OK?? Cool. In the meantime,

Re: No new group please!
Bill NZ0T, Now that makes sense. QCX,U3S,balloon flights..etc..separate sub topics rather than blended all together....good idea. Jim

Re: Taking another stab at getting my 80m QCX up and running
:-/ On a whim I replaced the ?P with one from another kit (never been set up). Set it to 80m, went to alignment, selected peak Bandpass, the reading was 5. C1 doesn't change it... Swapped the old ?P

Re: Taking another stab at getting my 80m QCX up and running
T1 is rewound and installed. There is no change in the bandpass peaking. C1 makes no difference. Peak value is 2 and about 3/4 of the bars. -- 73 NE5U Mike

Re: Difficulty winding and installing transformer T1 #qcx
QCX 40 T1 wound ok after I figured out which ends of the wires went in which holes, so they would just drop right in. My problem came from not RTFM and leaving a longer loop on the windings. If I had

True Blue seems to have rather quiet. Maybe he's keen not to let us know he's really John KM6HUV, who also posts as Hazada Masklo. I wonder who he'll be next week ? ;-) 73 de Andy
