OpenLRSng 100mW Range Test.

I read somewhere that this antenna has close to a spherical radiation pattern if the angle is right. I set the units to low power (1mW) and did some rotation while reading the RSSI values off the serial port. Seemed close enough to spherical for me.
I think the inverted vee that hams use is more directional because of the ground plane, also its inverted simply because its easy to put up that way.

Nagoya NA771 they are like $4 on ebay, might get one myself as a backup.
I am doing a video on the openLRSng code soon so might cover it then. Needs cleaning up but I might send it to Kari. try this:

Just change the three variablebuzzfreq lines.

uint32_t variablebuzzfreq = 2000; //declare at top

if (RF_Mode == Received) {
uint8_t rx_buf[4];
// got telemetry packet

lastTelemetry = micros();
RF_Mode = Receive;
spiSendAddress(0x7f); // Send the package read command
for (int16_t i = 0; i < 4; i++) {
rx_buf[i] = spiReadData();
}
//Serial.println(rx_buf[0]); // print rssi value
variablebuzzfreq = 2100 + (4 * rx_buf[0]);
}

uint32_t time = micros();

if ((time - lastSent) >= modem_params[bind_data.modem_params].interval) {
lastSent = time;

if (ppmAge < 8) {
uint8_t tx_buf[11];
ppmAge++;

if (lastTelemetry) {
if ((time - lastTelemetry) > modem_params[bind_data.modem_params].interval) {
// telemetry lost
buzzerOn(variablebuzzfreq);
lastTelemetry=0;
} else {
// telemetry link re-established
buzzerOff();
}
}
