    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

Hi guys, brought this to you cause of it's main part, aviation. But, it is a mix of wx report and Grundig receiver, 450dlx. I am receiving an automated wx report on 10048, it is very strong. It is also muffled. Is that the analog scramble I've read about, or is it my 450dlx? Thx

Ya lost me cheif,
No wonder... DLX doesn't do sideband.
What AB5R is trying to say is that you need a radio capable of receiving single sideband transmissions (SSB). You have to have your radio switched to USB (Upper Sideband) and tune it to 10051 to pick up the VOLMET from New York or Gander.
You're trying to listen to it in AM mode and it just won't work because the AM demodulator needs a carrier to work against to demodulate the incoming signal and since USB and LSB transmissions have no carrier, therefore no demodulation and no audio.

Don't you have BFO on that radio? If so, actvate it to get SSB voice. I am certain you are getting New York Radio volmet on 10051kHz usb.

:D



not sure how the BFO works on your radio there but I am guessing if you hit BFO on, you can then tune left to right across the width of that garbled signal till voice comes in clear?.
Only experience with BFO I had here is on my '75 Patrolman-9, and that doesn't have PLL digital tuning. I just have to tweek the tuner till it comes in right.

Looking at the specs, the Grundig 450dlx does not have a BFO or SSB capability.

It does have an IF output jack for possible future accessories.

Thx guys, the good news is-I do have a ferret antenna that goes to a uniden15X. THAT is perfect reception for planes, it just don't do the sidebands. As far as Alinco goes, it's in the works of getting 1. . Gotta get past HOHO time 1st.$$... Dang, they made ALOT of freq types over the years.. While I'm here, I wish to verify what I read in the RR wiki, somewhere. 138139.875 A.M is the refueler channel. Heard yesterday, and 2 days before, heard on the Uniden.. Oh well, fly high.
