ALC Comp:
Reads the gain in dB applied by the ALC algorithm. The gain is always <=0 in dB.
The minus sign is implicit.
CPDR:
Reads the power in dB after the compander, where 0dB is ideal. If the compander is not
enabled, it reads the same as Comp.
Off:
Used for debugging purposes or to save CPU cycles on slower machines.

(5) Band Selection & Band Stacking Memories
Figure 36: Band Selection
The Band Selection controls perform multiple roles in PowerSDR. First, when tuning the VFO to a
specific frequency the band indicator will move to the appropriate band (GEN if not in one of the
specific bands listed). This is used to quickly identify which band you are in, or when you are stepping
over a band edge boundary (see Figure 36).
Secondly, clicking on one of the Band Selection buttons will change the frequency, mode and filter to
the one last used on that band.
The third role is a feature called Band Stacking Memories. A single memory is defined as a frequency,
mode, and filter combination. Each band has several memories associated with it. Clicking on a band
button repeatedly will cycle through the available memories repeating from the beginning after the last
memory (hence the stacking memories). This is useful to quickly tune to various frequencies within a
band. To replace one of the memories with the frequency, mode, and filter of your choice, first click the
band button for the band memory you would like to modify. Then change the frequency, mode, and
filter to the desired settings (the frequency must be in the band selected). Finally click the band button
again to save the values.
The modified memories will be saved to the database upon graceful exit of the console. A crash will
prevent changed memories from being saved in order to keep faulty data out of the database.
Note :
Some band memory frequencies (such as 60m and WWV) are fixed in
software and cannot be changed.
