Auxiliary Features
In addition to the basic TX/RX circuitry already described, the
●Full compatibility with digital modes (data modes)
PSK31 and RTTY operations can now be performed with ease using PC software. The
External audio input/output terminals, separate from the mic and speaker terminals, are provided. For each of these the level can be adjusted in ten steps.
You can select special AF DSP filters for use with digital modes. Specially provided for PSK31 use is the choice of either a 1000Hz or 1500Hz beat frequency.
With the optional CW filters installed, you can choose between them even during SSB reception, which we have had many requests for.
It is possible to switch the VOX function so that it will respond either to mic input or to an external audio signal. No special standby wiring is needed for making digital use of this VOX function. When transmitting voice with PTT, external input signals are muted. Conversely, when transmitting using an external input, the mic input is muted; thanks to this feature, there is no need to disconnect the mic during digital mode operations. (Note that if you put an external input on standby using the mic PTT, it will not be modulated; sometimes users have queried as a possible fault, but it is not.)
●Features useful for 50MHz operations
You discover a DX CW signal during a USB band search! The
When scanning 50.110~50.150 with the SSB program scan, if you want to watch carefully at 10kHz intervals just use a slower scan speed. This is also possible with memory scan, but in that case you cannot hear frequencies in between. This allows you to set the scan speed slower by up to 5 points for selected frequencies.
The noise blanker, which has a reputation for being very effective in combating even weak noise, is now even better: we have added the ability to adjust the threshold level.
