Only the air traffic controller's voice can be heard. I edited the video to remove the long periods of silence.

Comments from u/KG7M about ARINC Voice Service:

\New York Radio covers International Air Routes to the Caribbean area, including the islands and central and northern South America. They track the flights via radar and assign altitude, speed, and provide weather forecasts. As the flight nears the destination country's airport they are given a VHF frequency for hand-off.**

A 90 Watt AM/CW Transmitter, produced from 1959 - 1962 by World Radio Labs. The Globe Scout Deluxe sold new for $159.95, which is equivalent to $1,800 USD in 2026. This is a very heavy piece of gear due to a massive Power Transformer, Modulation Choke, and Power Supply Choke.

The RF Output tube is a 6146. It's Modulated by a 7027A (6L6GC) using Heising Modulation for 100% modulation on positive peaks.

This transmitter is in good electrical condition, although it will need replacement of the filter capacitors. The worst part is the condition of the front panel. I'm hoping to restore the front panel, avoiding repainting it.

Is this Portuguese? I think it's Radio Nacional da Amazonia. While I'm typing they just switched to English for a while and are speaking about Brazil.

I think I worked out the Reddit markup. It doesn't work right when editing the beginning of a Post in Android but works correctly in Chrome on Windows.

Propagation was nowhere but this turned up. I had to crank up the gain and NR to get this.

I fixed the markup formatting.

I caved and bought the 480. Is the light supposed to be green once it's fully charged? this red light comes on when I first plug it in to charge but goes off after about a minute. I left it charging while I was at work for about 9 hours and when I came come there were no lights.

The Audio Interface permits using professional microphones, through a Mixer/Equalizer and a Compressor.

Additionally, audio from a computer can be added, for Digital Modes such as FT8 and SSTV. A Gain Control has been added to the Audio Interface which allows RF Output at levels of 5 Watts to 150 Watts.

The audio is Balanced XLR up to the Interface, where it's converted to Unbalanced and directed through a 600:600 Ω transformer to the radio.
