-====== MB7UBK - Fill-In Digi and iGate ======
+====== [CLOSED DOWN] MB7UBK - Fill-In Digi and iGate ======
-APRS local fill-in digi and iGate - still new and being tested and monitored.
+**NO LONGER OPERATIONAL**
-**Digipeating is temporarily disabled, iGate function still operating**. As most local packets are easily heard and repeated by the nearby MB7UG, digipeating even as a fill-in was really just wasting air time. The plan is to migrate to APRX which has a feature to delay the digipeating for a moment to see if something else does it first, this should allow true fill-in behaviour, only helping packets that are not already heard by MB7UG get out.
+MB7UBK was an experimental LoRa-VHF APRS Gateway, in combination with the LoRa-APRS digi/igate [[aprs:mb7uba|MB7UBA]]. It has been taken offline as 2m on this site is now being used by the packet node [[nodes:gb7bsk|GB7BSK]].
-Located in Basingstoke, Hampshire (IO91kg).
+**How it used to work:**
-Connected to the [[nodes:gb7bsk|GB7BSK]] packet node and BBS.
+Packets received on VHF were digipeated on LoRa from [[aprs:mb7uba|MB7UBA]], and packets received on LoRa were digipeated on VHF. This cross-band digipeating was done with the "directonly" setting in APRX for the VHF side, and rate limits were applied more stringently on the LoRa side.
+Also acted as a VHF Fill-In Digi, with a "viscous" setting of 5 seconds. This meant any VHF packets received were digipeated back on VHF only if they are not heard being digi'd by someone else in 5 seconds. The reason for this is the very well situated MB7UG is nearby, and this usually digipeats everything with no problem, so rather than waste VHF airtime by doing it again, the viscous delay means it will only act as a true fill-in, repeating what was not heard by anyone else who may do a better job.
-Eventual plan is to include a LoRa-VHF APRS gateway in combination with [[aprs:mb7uba|MB7UBA]]
