[Flexradio] Behavior of PEAK hold in Preview 12
Title: Behavior of PEAK hold in Preview 12 Eric et. al. I have noticed that if I have PEAK HOLD turned on when I am using the Panadapter that if I change the frequency the peak signal that was displayed stays in the display just shifted by the value of the frequency change. Let me try to explain better with an example. Say I am listening to a quiet band, 14.300 and the signal is flat @ -130 dB. Now a strong signal is present at 14.300, so with PEAK HOLD on I see a rise in the signal from 14.300 to 14303. If I move the VFO to 14.303, the 3 KHz rise in signal moves to the left of the center line in the Panadapter. Now another strong signal at 14.303 to 14.306 is present. At this point with PEAK HOLD I on, I now have displayed on my screen a 6 KHz wide increase in signal. This makes looking for signals much harder since if you change frequency the display stays cluttered with previous signal display. I suspect this is the way it works, but I think if you move the VFO you would want to erase the signal displayed by PEAK HOLD. In other words, if the VFO is changed, the display should be reset only if PEAK HOLD is engaged. This is the way my other radios that have a peak hold feature work. So, in a round about way I am asking for the current behavior of PEAK HOLD to be changed when the frequency changes. What do the other Flexers have to say about possibly making this change? -Tim --- Tim Ellison Integrated Technical Services Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell Skype: kg4rzy

Eric, I have noticed that if I have PEAK HOLD turned on when I am using the Panadapter that if I change the frequency the peak signal that was displayed stays in the display just shifted by the value of the frequency change. Let me try to explain better with an example. Say I am listening to a quiet band, 14.300 and the signal is flat @ -130 dB. Now a strong signal is present at 14.300, so with the AVG and PEAK HOLD on I see a rise in the signal from 14.300 to 14303. If I move the VFO to 14.303, the 3 KHz rise in signal moves to the left of the center line in the panadapter. Now another strong signal at 14.303 to 14.306 is present. At this point with PEAK HOLD and AVG I now have displayed on my screen a 6 KHz wide increase in signal. This makes looking for signals much harder since if you change frequency the display stays cluttered with previous signal display. I suspect this is the way it works, but I think if you move the VFO you would want to erase the signal displayed by PEAK HOLD.
