Frequency stability: +/- 30 Hz at 14 MHz over the range of 10 to 35 C, ambient with the transceiver in
the case or better with the TCXO active. (It can be much better than this.)
Available TX/RX modes: CW, USB, LSB, AM (full-carrier, double-sideband), SAM (double side band
reception) and FM. AM transmit and FM transmit/receive capabilities are available ONLY if the
"frequency translate" is activated (highly recommended)
FM options: Carrier (ultrasonic) squelch, sub audible tone encoding and decoding, tone burst ("whistle
up") generation, "narrow" (+/-2.5 kHz) and "wide" (+/-5 kHz) deviation and the selection of 7.2,10,12 or
15 kHz pre-detection receive bandwidths.
FM sensitivity for 12 dB SINAD, CCITT filtering:
7.2 kHz BW filter: -103.7 dBm (1.46uV) with 1 kHz tone at +/-1.5 kHz
10 kHz BW filter: -102.1 dBm (1.75uV) with 1 kHz tone at +/-1.5 kHz
10 kHz BW filter: -104.0 dBm (1.41uV) with 1 kHz tone at +/- 3kHz
12 kHz BW filter: -102.7 dBm (1.63uV) with 1 kHz tone at +/- 3kHz
15 kHz BW filter: -99dBm dBm (2.50uV) with 1 kHz tone at +/- 3 kHz
CW mode receive/transmit and frequency display details: Nine modes of CW display/shifting are
available to emulate the various makes of radios and suit the user's taste, ranging from no shifting,
display-only shifting, display and LO shifting and manual or automatic LSB/USB shifting.
In CW mode "CW-L" or "CW-U" is displayed depending on whether LSB or USB is being used for
reception.
CW Speed range: 5-48 WPM.
Available audio filter bandwidths in this firmware version: 300 Hz, 500 Hz, 1.8 kHz, 2.3 kHz, 3.6 kHz, with
a "wide" filter of 5, 6, 7.5 or 10 kHz being selectable in all modes except FM, where the filtering is done
prior to demodulation as noted above. All filters are software defined and additional bandwidths could
be made available. Filters can be used as BPF or as LPF selectable in main menu.
