GasFet preamp added TVC-449 rx
Greetings!
Today a fresh new ARR GasFet preamp was added to the 449.725 receiver at the W8TVC site.
The measured system sensitivity of the 449mhz receiver improved by about 10db. That's a nice improvement. [measured by putting the signal gen into the 6m antenna. 449mhz squelch opened at -40db before and -50db after the preamp was inserted in the system]
