Just looked and again I find that when I click on the button to download the
manual, the software gets downloaded.

Subject: [TenTec] Pegasus Programming Manual some Clarifications
> Greetings all:
> I have received a very nice email from the factory clarifying some of the
> items in the Pegasus Programming Manual. These clarifications are not
> errors as much as typos so I will provide them as follows.
> First I like the idea of an example for the more complex issues, such as
> frequency setting string.
> I choose the FISTS frequency as the sample.
> Using the notation of the manual then the string to represent 14.058 is as
> follows. NOTE that the frequency is expressed in MHz please.
> Tfreq is 14.058
> Mcor is -1
> Fcor, Bandwidth is 1050 (for this selected case), is 725
> Cbfo is 525
> Ctf is int(AdjTfreq/0.0025)+18000 'note the change from
> the manual please
> Ftf is ((AdjTfreq/0.0025)-(int(AdjTfreq/0.0025)))*2500*5.46 'note the
> change from the manual please
> ' the "mod" function is not always available so this formula works
> without it.
> Btf is int((Fcor+Cbfo+8000)*2.73) 'note again the change
> the manual please
> for the sake of saving some of your time the interim values of the
> calculations are as follows
> AdjTfreq = 14.0555
> Ctf = 23622
> Ftf = 2730
> Btf = 25252
> To get to the above number string for programming the frequency convert
> these last three decimal
> numbers to hexadecimal notation as laid out as described in the manual.
> Note the LSB is on the right.
> Note carefully the precedence forced by the brackets. I have checked them
> twice before letting this go, so they should be right now.
> Other items of interest
> Page 20, Keyer Timing
> delete the word "(double)" and then things will look better
> Page 21, Noise Reduction and Automatic Notch
> The second "nr =" should read "an ="
> The factory confirms that the Automatic Notch works in the CW mode which I
> find beyond my ability to comprehend. If the Automatic Notch works on CW
> then why does it not attack and remove the desired CW signal your trying
> copy? I must have a comprehension problem of what Automatic Notch does,
> for the
> moment it is beyond me and my skills to understand, sorry 'bout
> Page 21, Transmit Audio Source Select and Mic Gain Settings
> the source is controlled by an ASCII character a "0" (zero) or a "1"
> The gain range is from 0 (0x00) to 15 (0x0F), note the Hex expression of a
> binary value.
> There are some other items of possible confusion, but they should be
> in terms of the above and treated accordingly.
> I do not have a Pegasus radio here to try these things on, wont have one
> until I first sell my Scout etc. The Pegasus programming protocol is not
> complex, in terms of other similar types of protocols used to make "boxes"
> do things. I am looking forward to using a Pegasus in my vehicle with a
> game paddle controller down the road. The low level control of this
> not hidden behind the yacomwood protocol limitations will let new models
> how the radio functions come forward, I for one feel this is a great step
> The manual on page 2 suggests that TenTec will be creating DLL's , VBX's,
> and Active - X tools so that these tools can be a "drop-in" to other
> software. This is a great start to getting beyond today's yacomwood
> protocol and the limitations it imposes on host programs such as various
> logging and contest operating programs. I for one would be glad to
> participate with others in the development of a common DLL language that
> would permit one to plug in a TenTec, Yeasu, ICOM, or Kenwood radio into
> of the compatible Logging and Contest programs. There are some tricky
> issues to be resolved but they are not insurmountable. Please email me
> directly if your interested in working through these issues from the
> software development side.
