Sadly, I am moving to Eagle and had to take the MERIDN digipeater off the air.
SHAFER has great coverage now and so a fill-in digi isn’t really needed.
I’ll implement an Igate at the new house for routing packets to APRS-IS.

I bought a Anker Soundcore bluetooth speaker to use with my FT3DR, but it won’t pair.
The FT3DR “sees” the Anker speaker, but when I try to connect, it tries for a while, then fails.
Will look for another speaker.
Did you know you can send/receive messages from APRS to the SMS network? Super easy.
Just compose a message to:
Start the message with @(the destination phone number) (space) (short message). Example, if I want to send the message “test” to phone # 123-456-7890, then the message will be:
SMS users can reply, as long as you are still within range of the digi that heard your beacon.
I use an Easy Digi interface between my Icom IC-2300, Direwolf & APRX. Here is my PTT string for my direwolf.conf file for Push To Talk:

SHAFER provides reliable coverage along I-84 from Mountain Home to Ontario, OR. To the south, most of the valley including the northern face of the Owyhees. And to the north, sporadic coverage in the mountains and along Hwy 55 to Horseshoe Bend.
Near Cascade, SNOBNK provides broken coverage in the Boise mountain range and along Hwy 55 from Smith’s Ferry to McCall. To the west, it covers I-84 in Oregon as far as Ontario.
In the Boise area, MERIDN Fill-in digi provides coverage along the foothills and in town. MERIDN IGates all traffic, but only digipeats over the air if MERIDN hears it direct *AND* mountaintop digi’s don’t digipeat the beacon (using APRX’s “viscous-delay” feature, set to 5 seconds). This prevents MERIDN from adding noise unnecessarily.
CNABAR, previously in the Owyhees to the south, will hopefully return at some point to provide coverage down Hwy 95 and into eastern Oregon.
For Handheld Radios (HTs)
WIDE 1-1,WIDE 2-1
The first path is for fill-in digi’s. The second path is for mountain-top digi’s. Central and southern Idaho has enough IGates and wide coverage that one mountain-top beacon is usually sufficient to get your packet to the Internet.
For Mobile Operators
WIDE 1-1,WIDE2-1
Same as HTs, this will get you beaconed by fill-ins, plus one hop from mountain tops, which will usually get you gated to the Internet. If you use WIDE2-2 in the Treasure valley, your beacon will likely hit SHAFER, then SNOBNK (into McCall) and BKRCTY (into La Grande). If you need direct receipt of your packets that far away, just realize you are lighting up several mountain digi’s to accomplish that.
For Base Stations
WIDE 2-1
If you are beaconing from a fixed location in the Treasure Valley within earshot of SHAFER, I recommend using the path WIDE2-1. No fill-in digi path needed. One hop from SHAFER will certainly get you IGated.
For High Altitude Balloons
(Don’t specify a path)
If your beacon will originate higher than ~10k ft, then you don’t really need any digipeater path in your config. It will be heard by multiple IGates and routed to the Internet. If you are (rightfully) concerned about when it drops below average terrain, then see if your tracker has the feature to change the path based on altitude.
At MERIDN, I have elected to IGate all balloon packets, but not digipeat them. On multiple occasions, balloons have passed over at 70k ft using a WIDE2-2 path every 30 seconds and as a result have caused congestion for hundreds of miles. With that altitude, they can be heard from Vancover to Vegas to Salt Lake City.
Thanks for providing this service. The SHAFER digi has good coverage for most of the valley, but much of the foothills are in its shadow. Users on the southwest side of the Boise mountain range need help getting their signal out. However, for a long-term configuration, I recommend you use the “viscous-delay” feature from APRX so you aren’t repeating packets already beaconed from SHAFER or other digi’s. As an alternative, if you’re using Direwolf, you can set it to only digipeat WIDE1-1 packets.
I often hike & bike near Boise with my HT set to beacon. Sadly, in my experience, 5 watts is not sufficient for most packets to get IGated, even if you feel like you can see the mountaintop digi for most of the outing. Yes, some get through, but I wouldn’t count on much of your journey getting tracked. Anecdotally, it seems better to just stop near a summit, do a manual beacon and listen for your repeated beacon to be sure something went out.
Did you know APRS.fi can send you alerts when a station goes off-air or on-air?
Just visit https://aprs.fi/my/ and add a station under “Stations I follow”
From there, you can edit the settings to send you emails when certain events happen. Example:
It’s pretty easy to clone a Raspberry Pi SD Card on a Mac, but takes a LONG time (32GB took 3 hours to backup and 10 hours to restore via my iMac).
I recently bought a Kenwood TH-D74 for hiking and APRS use. I had seen anecdotal complaints about the battery life around the web, but had not seen any real world data. So I setup a test and timed the battery performance.
I started with a fully-charged, stock 1800mAh battery.
Settings:
In short, nothing major was draining the battery other than the APRS beacon.
Result: 8 hours
