Transverter offset

Gents,
happily using LOG4OM with my TS2000. However, is there a transverter offset hidden away that would allow the freq to be correctly read when I have a 4M transverter connected? I have the transv feature enabled on the TS (and it correctly displays 70.xxx) but the logging prog is reading the IF only
Regards
Paul

Not at this time Paul but I will look into this.
What are you using Hamlib or Omnirig?

Thanks Terry, using Omnirig.

Hi Paul,
Having looked into the possibilities I see there is no transverter support in either Omnirig or Hamlib, this means that we need to provide an offset facility for transverters in Log4OM. I have now added this to our mantis list for a future enhancement.

Transverter offset is possible in Omnirig, you have to create an .ini for it, as an example i will only show the changed lines for my set (TS-590)
My transverter has an oscillator of 41MHz, and transverts 29MHz from and to 70 MHz
Code: Select all
[pmFreqA]
Command=(FA...........;)
Value=2|11|vfText|1|-41000000

-41000000 is the value of the oscillator and since it is minus, it is subtracted from the frequency in Log4OM and then send to the transceiver, so 70.200 in Log4OM becomes 29.200 and sent to the transceiver
Code: Select all
[pmFreqB]
Command=(FB...........;)
Value=2|11|vfText|1|-41000000

Same story for VfoB
So far the direction from Log4OM to Transceiver
In the other direction these line have changed
Code: Select all
Value1=18|5|vfText|1|41000000|pmRitOffset
Value2=2|11|vfText|1|41000000|pmFreq
Value1=2|11|vfText|1|41000000|pmFreqA
Value1=2|11|vfText|1|41000000|pmFreqB
This controls that 41 MHz is added to the frequency received from the TS-590. So if the transceiver is set to 29.200, Log4OM receivers and displays 70.200 MHz
If i want to use the transverter i just load the ini file from within Log4OM clicking the headset icon and select my TS-590-transverter.ini file.
Hopefully you get the idea, it works globally the same for all transceiver .ini files

As i also have a FT-897 i can give you the .ini here also.
for setting the frequency:
Code: Select all
[pmFreq]
Command=00000000.01
Value=0|4|vfBcdBU|0.1|-4100000
ReplyLength=1
[pmRitOffset]
Command=00000000.F5
Value=0|4|vfBcdBS|0.1|-4100000
ReplyLength=1
The FT-897 uses 10 Hz frequency steps, so it -41000000 becomes -4100000
For reading the frequency
Code: Select all
[STATUS1]
Command=00000000.03
ReplyLength=5
Value=0|4|vfBcdBU|10|41000000|pmFreq
Change the Add/Subtract frequency to your own need. i.o. enter the offset frequency of your own transverter
If your transverter operates below the transceiver frequency then exchange the minus sign. e.o. positive becomes negative and vise versa
