QRG offset for transverters, auto-select rig by band

It would be very nice, for those of us who use transverters to work the VHF/UHF bands, if it were possible to enter an offset to the freq read/written to the radio to = the transverter output freq. For example, to work 144.200 MHz, my "IF" rig is tuned to 28.200 MHz, so adding 116 MHz to 28.200 would enter the correct QRG into the log and onto the TRX window.

Along those same lines, it would be cool to be able to auto-select between rig 1 and 2 based on the band selected. For instance, I use one rig for 160-10m, another for 12, 30 and 17. Or, I might use one for HF and the other for VHF, etc.

I enjoy the heck out of this program, and would be happy to do what I can to help its development.

Transvertor Offsets

I'd also like to see this feature. For me I use a 4 Metre transverter with an FT2000 using a 28Mhz IF. This requires a 42MHz offset to correctly display 70MHz.

Re: Transvertor Offsets

This is very interesting but I have no idea how it should work. I don't have any experience with it. I see that you want to add offset but for each band or add one common offset? How does it work in other programs?

In Ham Radio Delux provides

In Ham Radio Delux provides an Offset button provides for the entering of any offset frequencies for transverter use as well as the algorythm for computing the frequency and will seperate display will indicate the calculated transmit frequency. so when you set up the Offset function you enter what amount you want added or subtracted for the band selected. e.g. 28Mhz Add 116Mhz. This will cause 144Mhz to be selected whenever the Offset button is clicked when operating on 28Mhz. I guess this becomes more complicated when there are two VFO's so to be able to set up for VFOA and VFOB *Might* useful. And of course the computed 144Mhz must be entered into the log when the Offset button is pressed. Make sense ?

From Logger32 ver 3.19.0 it

From Logger32 ver 3.19.0 it is now possible to add (or subtract) a fixed offset frequency to that obtained from the CAT controlled radio. As Logger32 can control up to two radios, provision is made to allow the addition of different offsets depending on which radio is “active” at the time.

The option will work alongside all other frequency related features of Logger32 – such as the DXSspot window, $QSY$ macro, etc.

More info on this feature in Logger32 can be found here: http://www.logger32.net/help/index.html

I'm still very interested in

I'm still very interested in this, any chance this can move to the "To Do" list?

Re: I'm still very interested in

Dave,

it's already on my todo list but I was not sure how to add it to program. I must look at logger32 manual how it does that.
