nbfd23,
I just went through this...
You will need:
1. KPG-D1N_V510 software (radio programming software)
2. KPT-300LMC_V201 (kenwood's License Management Client)
3. Install #2 and then #1.
4. Open #2 and you will drag and drop the license file for the KPG-D1N_V510 authentication: DEALER_KPG-D1N_W_xxxxx.jkefs. The 'W' means the entitlement to program wide FM frequencies such as for AMATEUR RADIO. I cannot remember the exact procedure. There are a lot of youtube videos on this. There is a series by specialty communications. At this point you can start programming your radio; however, you will NOT be able to 'activate' entitlements/features for which you bought licenses for until you complete step 5.
5. Once you are done with #4, you HAVE to authenticate/create 'your account' with Kenwood if you wish to add entitlements/features to your radio(s). To do this, you drag and drop: KWD-ACT___xxx.jkefa into the KPT-300LMC_V201. Again, I cannot remember the exact procedure although I just did this last night. Go look al specialty communication's youtube videos.
If anyone else wants to correct my write up please do so. I'd hate for other people to go through the same struggle I went through.
