Loose Notes 2/12/16

  I'm just catching up on the developments over the past couple of weeks. Some interesting stuff has been going on, and a few minor developments are worthy of mention. 

FM Repeaters 

• Per K0UMM (Travis), the VHF SuperLink repeater on 147.015+ in Collegeville (near St. Cloud) is "sickly". Travis rang up the machine for a "noisy S1" from less than 13 miles away. More troubles for the crumbling SuperLink network. Even worse, he also noted that the 146.940- in Sauk Rapids is "off-air". No mention of these problems on the St. Cloud ARC's website, but it appears that they're raising money for a new repeater. No mention as to which repeater they are raising money to replace. 

• Near Albert Lea, the 146.880- (100.0 PL) wide-area two-metre repeater is back on the air. Also in that same area, the 443.525+ (100.0 PL) is reported as back on the air. 

• The 462.675+ GMRS repeater in Crystal is down. Per N0RVY (Steve), the transmitter has failed. No timetable for restoration at this point. 

DMR 

• The big news in the local DMR world is that N0AGI (Nagi) and N0BVE (Don) have moved the 442.175+ machine in Prior Lake to Faribault. More information can be found in Nagi's blog post on the subject. Don and Nagi were reportedly able to access the repeater continuously on the drive back to Prior Lake using an HT and an external mobile whip. The site in Faribault is much higher in elevation and the tower is higher than the (currently abandoned) site in Prior Lake. A Yagi is currently beaming the signal towards the metro, but that will switch over to an omni vertical in a few months. This move comes as a big surprise, but the Prior Lake site didn't really reach well north of the Minnesota River. It's possible that operators just south of the metro will have to upgrade their rigs and/or antennae once the repeater switches to a vertical -- especially as the leaves come in. 

APRS 

• W0YC-5, the major metro APRS gateway, was down for about two days last week. Fortunately, tropospheric conditions weren't overloading the metro with distant traffic, and we've gained adequate redundancy to handle these failures without collapsing. 

•  AE0MT-10 is back on the air as an RX-only I-Gate in Coon Rapids after an absence of just under two weeks.  

• Though the month of February is still young, two RX-only gateways have racked up impressive stats. KE0NA-11 in NE Minneapolis has gated over 1300 packets so far, while N0KFB in Mounds View has handled nearly 5000 in the same period. Both of these gateways are operated out of homes with rooftop antennae. It really can be done.
