[TenTec] Paragon Question

[Ken Brown]

The narrow filters in the Paragon are all in the 6.3 MHz IF, which can 
be shifted in frequency space using the PBT control. You should be able 
to zero beat (that is get the audio note frequency of the incoming 
signal equal to) the incoming signal to your CW sidetone, using one of 
the wider filter selections, then switch to a narrower filter and adjust 
the PBT to maximize the signal strength of the signal you have 
previously zero beat.

You don't need to zero beat the incoming signal, though it may be 
preferable to do so. Whatever audio tone frequency you like to hear from 
the incoming signal, you can adjust the PBT to maximize when using the 
narrow filters.

Zero beating as described above should make your transmitted signal zero 
beat with the other station you are attempting to communicate with. 
However it depends on your BFO frequency and your sidetone frequency, 
which are BOTH adjustable. The Sidetone frequency can be adjusted with a 
pot on the back panel of the rig. Since that is fairly easy to access, 
it is also probably the more likely one to be misaligned.

Read the manual and be sure you understand what you are doing before 
adjusting the sidetone. Some thing goes for the BFO, but even more so, 
because it can affect your transmit frequency too. It would be best to 
have a frequency counter available when making either of those adjustments.

None of these frequency adjustments for getting zero beat with the other 
station are really necessary in order to get a desired received signal 
audio tone frequency in the center of your narrow IF filter bandpass. 
That is done with the PBT control.
