SZ2RLF D-STAR REPEATER INSTALLATION

SZ2RLF D-STAR REPEATER

DSTAR and ANALOG Test

K6IRF and W6BMX testing the signal and audio quality of the Dstar compared to an analog.

DV Node adjustments

This video was a quick attempt to explain how to set up the NQSM Hotspot from NI2O. I am working on putting a more focused and professional version. Anyone that might help with video editing would sure help the project along.

Receiving Digital with SDR-Radio and DM780

This video shows how I connected SDR-Radio to Ham Radio Deluxe using Virtual Serial Port Emulator and Virtual Audio Cable programs to receive digital mode transmissions. A virtual Audio Repeater program was used to monitor the Receive audio. I hope this is useful in explaining how to use virtual ports and cables. 73, N7JFP.

Paket radio / Kantronics KAM grounds

Found this little noise on 10meters and figured i would track it down, it was closer then i thought, noise was from my paket TNC.

D-Star vs FM under impulsive noise conditions

This video shows the performance of FM vs D-Star under impulsive noise conditions. It is clearly audible that D-Star works without problems when FM is hard to understand.

The transceiver is a modified former C5 C-Net phone with DVmodem by DO1FJN. The test signal was provided by DL3OCK. It contained the same voice information in D-Star and FM modulation on two different channels

D-Star vs FM in weak signal condition

This video shows the comparison between D-Star and FM at around -115dBm.
It is clearly audible that D-Star has some advantages against FM if the decoder can stay in sync. The microphone of the camera does not represent the FM very well. In reality the FM sound was slightly better.
