b7543dce08 When SNR>90 dB is specified, simulated signal is noiseless. If Doppler spread is nonzero, then signal will have random peak amplitude. In this case normalize the signal so that peak amplitude=32767.

d48fb58ffa Enhance jt65sim to allow 11025 Hz rate, selectable base frequency and o/p gain offset. 
Needs a review.

d1be2506a9 Several enhancements to DXpedition mode: 
1. Insert dummy report when Hound is called by complex-callsign Fox.
2. Allow Fox to transmit anywhere between 300 and 900 Hz.
3. Restrict randomized Hound freq to the range 1000 - 3000 Hz.
4. Suppress Fox signals that would be duplicates.
