These are the transmit profiles that I am using with
the current CFC Audio Tools version of OpenHPSDR mRX PS. That
means that they will only work with version 3.4.1 or later! You
can preview them in the short videos below to see if there is
anything here that interests you. I get excellent reports for
clarity and good fidelity with all the profiles but keep in mind
that you should make appropriate level and EQ changes to optimize
the imported profiles for your voice and audio setup.
Right click on the links below and choose the "Save As" option to
download whichever collection of TX profiles you would like to try
out. Note that all of these profiles utilize the CFC Audio Tools
and are optimized for my external audio rack, which is set to
produce a flat audio response. This doesn't mean that it won't
work with your audio source, however, to get the best result you
might need to adjust the PRE EQ (Equalizer) to flatten out the
audio response of your audio source. All of
the profiles utilize the VAC1 input path, so if you are
using either the MIC IN or the LINE IN path, you would
need to click on the VAC1 button to disable it, and then
go to the Transmit tab in Setup and select the audio
source you wish to use. When that is done, save the
profile and it should work with your audio source path.
Obviously, you should observe the MIC level with the TX
Meter to make adjustments to the MIC gain so the level of
your audio source is optimal. These steps will be
necessary for each TX profile that you import.
The first TX profile archive contains eight different SSB profiles
from 2.8K to 3.8K.
This archive file contains the transmit profiles shown in the list
below. Each profile that you wish to use will need to be imported
individually into OpenHPSDR mRX PS using the procedure outlined at
the bottom of this page.
SSB 2.8K VAC1 (100 to 2900)
SSB 3.0K VAC1 (60 to 3060)
SSB 3.1K VAC1 (60 to 3160)
SSB 3.2K VAC1 (50 to 3250)
SSB 3.3K VAC1 (50 to 3350)
SSB 3.4K VAC1 (50 to 3450)
SSB 3.5K VAC1 (50 to 3550)
SSB 3.8K VAC1 (30 to 3830)
The video below is provided to give you a preview of what these
SSB profiles sound like with the ANAN-200D driving my ALS-1306
amplifier to 1KW.
If you already know your way around, the steps below should be
enough to get you going:
After extracting the transmit profiles from the zip archives, to
import a profile, click on "Import Database" at the bottom of
the OpenHPSDR menu and then browse to the location of the
extracted profile(s) on your hard drive as shown in the image
below. Select the profile, and then click on "Open".
automatic profile utility will import the transmit profile
into the correct part of your database.xml file. Note that
OpenHPSDR mRX PS will shut down and prompt you to restart
OpenHPSDR mRX PS each time you import a transmit profile.
Note that if you are using
the MIC IN audio path and a microphone that requires the
20dB boost option you will need to enable that option
manually and then save the profile. Also, if the ALC
Comp meter does not show several dB of ALC compression
during normal speech, an easy way to increase the
over-all gain going into to the CFC components would be
to increase the Leveler Max Gain setting from the
default 5 to a slightly larger value. As an alternative,
you could increase the CFC POST GAIN slider until you
see the desired ALC Comp response.
