 ====== MB7UBK - Fill-In Digi and iGate ======
-APRS local fill-in digi and iGate - still new and being tested and monitored.
+Experimental LoRa-VHF APRS Gateway, VHF side - LoRa is sent via [[aprs:mb7uba|MB7UBA]].
-**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.
+Packets received on VHF are digipeated on LoRa from [[aprs:mb7uba|MB7UBA]], and packets received on LoRa are digipeated on VHF. This cross-band digipeating is done with the "directonly" setting in APRX for the VHF side, and there are rate limits applied more stringently on the LoRa side (though normal traffic for the area is well within these limits).
-Located in Basingstoke, Hampshire (IO91kg).
+Also acts as a VHF Fill-In Digi, with a "viscous" setting of 5 seconds. This means any VHF packets received will be 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.
-Connected to the [[nodes:gb7bsk|GB7BSK]] packet node and BBS.
+Located in Basingstoke, Hampshire (IO91kg).
-Eventual plan is to include a LoRa-VHF APRS gateway in combination with [[aprs:mb7uba|MB7UBA]]
