While using the equipment, the frequency range is for the device is 10kHz to 30MHz.
The TS-8505 functions competently across numerous transmissions modes including SSB, AM, FM, CW and FSK.
A: An Automatic Antenna Tuner (AT) is already built-in to the device.
A: The power output maximum does stand at 100W, but only to SSB mode.
A: So in regards to the reference frequency stability of the device, the best it can do is a range of -10 to +50 which can go up to 10 PPM. This is with the TCXO, which unfortunately costs extra, but does provide 0.5 ppm stability.
A: Yes you can, as the TS-8505 does allow you to change and adjust the filters that are accommodating to you.
