Example:
• The current Panadapter is tuned to 50.125MHz
• There is an external 144 to 28MHz transverter on a FLEX-6700 with an internal 2m band
• The most recently used 144MHz band is the external 144-28MHz transverter
• A direct frequency entry of “144.2” is typed
• The radio will select the external 144-28MHz transverter and tune to 144.200MHz
• The Panadapter will clearly indicate the selected band by placing a “144” (or whatever name
was given to the transverter band) in the upper right of the Panadapter If this is not the
desired result -- if you intended to switch to the internal 2m band, just use the Band selection
to switch to this band in the Panadapter. At this point, the radio will switch to the correct
band and it will become the “favorite” band next time a direct frequency is entered.
27.3 TRANSVERTER POWER SETTINGS
The operation of the RF power slider in SmartSDR is set by the Max Power setting in the transverter
setup. Setting the RF power slider to 100 will set the power to the Max Power setting. The zero
setting will shut off all RF power from the transverter port. A setting of 1 would be 20dB below the
max power. For example, if a Max Power setting of +5dBm was set in the settings, the slider “0”
position will be no power, “1” will be +5dBm - 20dB = -15dBm. The 50% setting on the slider will be
+5dBm - 10dB = -5dBm.
27.4 TRANSMITTING ON A TRANSVERTER
When transmissions occur on the transverter, the radio will reconfigure internal relays to connect
the exciter in the FLEX-6000 to the XVTR port on the radio. If a split IF is in use, the RXA or RXB port
may continue to be used for receiving if your transverter continues to provide receive RF (check with
transverter manufacturer).
When a common IF transverter is used, the XVTR port normally being used for transmitting will be
switched away from the FLEX-6000 SCU and connected to the exciter. As a side-effect, the relay may
connect the SCU to one of the HF antenna ports which causes the Panadapter to show HF signals in
the HF IF band in addition to the transverter band when transmitting.
In addition, when transmitting on a split IF transverter configuration, because the transverter RF
output is low power it will not be dramatically visible on the transverter Panadapter like it is shown
when transmitting on HF at high power.
Both conditions during transmit can be quite confusing as they do not accurately represent the
transmitting state of the radio properly. For this reason, the Panadapter will pause when using IF
transverters while transmitting.
