I tuned in a moderately strong AM signal at the top end of 160m this evening. It was playing hits from the mid 1960's, but no voice announcements. Fairly good audio, but just a little short of broadcast quality. I first tuned it in about 0515 GMT. It kept going strong until it played its last song and cut the carrier at 0600 GMT sharp.

I heard a similar station on 7295 two weeks ago.

It could be harmonics from a 'Part 15' home broadcaster. I have one that I use for 'homecasting' to my antique radios. The harmonics can be stronger than the primary because the short legal length antenna radiates more efficiently at higher frequencies. The Pi net in the output must be tuned properly.

Those DAM pirates and their non-broadcast quality transmissions.
Stand out!!!!
Go to full legal limit and the loudest audio that rattles speakers around the whirl.

Unlikely to be a harmonic from a Part 15 AMBC transmitter. Too strong for 160, and too stable for a simple oscillator, and coincidentally, precisely on 1995. Also, it was much better on the beverage than on the indoor loop or 75m dipole, indicating it was hundreds of miles away, to the north or northeast.

No one up here ever does anything like that. Someone must have moved your beverage as a gag. Go check it out. |

Aft Don and the rest of the gang..Don heard it here too at about S2 or so..not very strong..been on there b/4..always figured it was a harmonic..maybe once or twice a week..maybe not....not 100% sure about terratorial limits out in the ocean but seem to recall that it's 200 miles or so from the coast..OK Steve about 7295..har har now it might be a good comment if we could get the SW broadcasters to saddle up and move out..they do create their own version of chaos there aft and evenings for sure
By the way Don I've mentioned this b/4..ur always strapping up here on the re-vamped SX140..notice you do lots of chit chatting around 3.680 or so more often than in the ghetto..as Martha would say "it's a good thing" 73 de DAVE

The real questions are: Did it sound like 15,000 CLEAR watts? Was it Kraco or Bird watts? (I'll give it a listen tonight on the Bevs too, Don) T |

Use an "AM Courtesy Filter" to limit transmit audio bandwidth +-4.5 KHz, +-6.0 KHz or +-8.0 KHz when needed. Easily done in DSP.

No one up here ever does anything like that. yeh, what he said. The NE gang reads Part 97 every night like little kids read their prayers before they jump into bed. There's no doubt. Was it Kraco or Bird watts?  Kraco watts. Tom, you slayed me. That's thinking outside teh box OM. I dont think they ever actually made a wattmeter tho. How about Vanco Watts? This is QUALITY. |

I resemble that. I have one and it is dead nuts on compared with my calorimeter which in turn is calibrated against the NBS US standard (pictured.)

they probably use bird 43's on the assembly line to calibrate them.  |

If you burned off a PL259, you were probably doing something wrong, like running your rig into a short. Dosey watts is what you want. |
