The suggested path is not quite right. It would have to begin with the call of the digipeater, in your case N4SRN-1. I think that would work for your D74, but would also digipeat any non-specific paths the D710 hears (relay, WIDE, etc.) There are a couple of other possibilities:
- Use the path TEMPn-N on your D74 (choosing n and N as you would for a WIDE path, based on your desired coverage). This would let anyone using a TEMP path be digipeated, so you might get a few other hikers, but I think not many people are aware of TEMP.
- Look at the NETWORK setting. If you pick a unique ALTNET for your two radios, I think that would keep your digipeater private to you. However, I'm not sure how this would affect further digipeats beyond your D710; this needs some research in the manual.
