# Gqrx Panadapter
# Gqrx Panadapter (uBITX panadapter version)
A [Gqrx](http://gqrx.dk/) to [Hamlib](http://www.hamlib.org) interface that
keeps the frequency displayed in Gqrx synchronized with the frequency settings
on your radio.
Authors
Original version: Alexander Fasching, OE5TKM
uBITX version: Rob French, KC4UPR
The IF output of the radio should be connected to a SDR, which is then received by Gqrx.
This script continuously reads the frequency of the radio from ```rigctld```
and sets the LNB setting Gqrx.
A [Gqrx](http://gqrx.dk/) to [Hamlib](http://www.hamlib.org) interface that keeps
the frequency displayed in Gqrx synchronized with the frequency settings on your
radio. This version allows for bidirectional control: if the frequency is changed
on the radio, then it will be updated in Gqrx, and if a new frequency is selected
in Gqrx, then the radio will be tuned to that frequency.
The IF output of the radio should be connected to a SDR, which is then received by
Gqrx. This script continuously reads the frequency of the radio from ```rigctld```
and sets the LNB and frequency settings in Gqrx. In addition, if a new frequency
is selected in Gqrx by clicking on the waterfall, then the script will command a
new frequency to ```rigctld``` to update the radio's frequency.
## Usage
```
gqrx-panadapter.py [-h] [-g P] [-r P] [-i T] [-f F]
gqrx-panadapter.py [-h] [-ga A] [-gp P] [-ra A] [-rp P] [-i T] [-f F]
optional arguments:
-h, --help show this help message and exit
-g P, --gqrx-port P remote control port configured in Gqrx
-r P, --rigctld-port P listening port of rigctld
-i T, --interval T update interval in milliseconds
-f F, --ifreq F intermediate frequency in MHz
-h, --help show this help message and exit
-ga A, --gqrx-address A address that Gqrx is listening on
-gp P, --gqrx-port P remote control port configured in Gqrx
-ra A, --rigctld-address A address that rigctld is listening on
-rp P, --rigctld-port P listening port of rigctld
-i T, --interval T update interval in milliseconds
-f F, --ifreq F intermediate frequency in MHz
```
Make sure you configure [remote control](http://gqrx.dk/doc/remote-control) in Gqrx.
