The software is pretty comprehensive and offers tons of bells and whistles. The only bug with HRD and the DX-SR9 that was noticed is the Power button label text did not change to reflect the current power setting. This should be corrected in a future update. HRD is currently on sale for $10.00 off it’s normal price of $99.
The good news for DX-SR9 owners is that you can use HDSDR as a front end to Ham Radio Deluxe for tuning by enabling the HRD DDE interface within HDSDR. The bad news it appears that there is some issues with the DDE interface that won’t allow HDSDR’s “Enable Transmit Button for DDE” feature to work. The button will appear, but won’t put the radio in to transmit. The work around is to just use HRD to enable transmit. Best guess is that HRD’s DDE interface has changed some over the later versions. Maybe this will be cleared up in the near future.
