Circa 1985 Yaesu FTV 707 transverter.
10 meter all mode rig used as the tuneable IF.
This was an option for the FT-707 transciever.
It requires no more than 1 Milliwatt drive on 10 meters.
that's .22 volt ( 2 tenths) into 50 ohms. Driver output from earlier tube
rigs like the FT 101 or 901 are NOT suitable. All but the most modern rigs will require an attenuator to keep from destroying the transverter.
RF output is rated at 10 watts SSB, CW, FM, and 2.5 watts AM carrier
( the manual says 5 watts but that = 20 watts pep... almost certainly wrong!)
Sensitivity is show as .5 uV and .25uV. We think 1/2 microvolt is in keeping with the age of the transverter, and most likely the correct figure. No noise figure is given . We'd guestimate somewhere in the 1.5 to 3 db range.
10 meter input and output use different ports... so do NOT blow up your transverter by transmitting into the 10m output jack ( the coax connector).
The next video will test the transmitter section, and explore the cause of distortion and apparent instability of the received signal in this first test, probably using an FT-817 and FR-450 as the driver and reciever.
