Not able to control RX side of Remote SDR with GPredict

[genepool99]

I activated the Gpredict integration and can only control the TX side of the radio.

EDIT: After further experimentation, the receiver side of the radio can be controlled if you first tune it manually to be very close to the desired auto-tune frequency.

Reproduction Steps

1. Restart RemoteSDR to turn the GPredict option on
2. Setup receive and transmit interfaces in GPredict as described in the documentation
3. Click "Engage" and "Track" in GPredict
4. Observe the Tx being correctly controlled by RemoteSDR, but not the Rx. The GPredict icon briefly displays for Rx and Tx, then Rx disappears.

System

1. Remote SDR v5 Pi image
2. HackRF One SDR
3. GPredict runs remotely on the same LAN (but locally running GPredict was also tested with the same result).

Additional Information
A Nmap scan of the Remote SDR Pi shows a listening port 8007 but not 8006
