Typically, yes -- you'll have to find a compromise setting that works for both modes, or reserve the unit for just a single mode.

Re: Changing WiFi AP on already-configured boot image

I'd think the Mac should, at least, show the small FAT partition on the SD card (it may or may not show the EXT3 or EXT4 partitions) -- THAT, if I recall, is the BOOT partition (containing the model specific device trees, etc.) and is where the generated wpa_supplicant information file should placed...

Re: RF Hangtime, DMR (Repeater)

To my knowledge, the various "hang times" only really become effective if you are operating mixed mode (D-STAR and DMR on the same board). They control how long the Pi-Star software stays in the last used mode ("listening DMR", say) before going into an all mode wait ("liste...

Re: MMDVM hotspot ,TX problem

Sorry if I misunderstood your question, but I unfortunately just can't tell you what the Pi-Star dash board shows for BER. This is because my hotspot plainly ignore ANY Tx signals from any of my radios. The hotspot does not respond to my radios. I checked the radios, separately cheched each one of ...

Re: MMDVM hotspot ,TX problem

My hotspot runs a DV-Mega board, which is not supported by the MMDVM calibration routine. Calibration is used to fine-tune the less-than-ideal MMDVM frequencies to better match the frequencies programmed into the radio; too great a mismatch and the BER will be extreme. Note that, with two radios, it...

Re: MMDVM hotspot ,TX problem

You mention TS1 and TS2... To my understanding, the only boards which make use of both time slots are the "dual" (and not "dual BAND") versions. These operate as mini-repeaters, not plain simplex hotspots. If so, your channel configurations will need to incorporate the correct of...

Re: Can listen but not talk out

Two things... Make sure the 7100 is on its LOWEST power setting if you are anywhere near the hotspot (even 1W is a massive hit -- my HTs are set for <1W and the 5100 is in the rust-bucket while the hotspot is inside my faraday cage of a house [metal roof, metal siding] over 30 feet away). Second -- ...

Re: Limits on a Multiple DMR Gateway

Since Brandmeister has only a small handful of 7 digit talkgroup id's, and tgif has 50, and think I will try and redo the gateway rules so TGIF is the default, and Brandmeister requires a prefix.. Unless things have changed -- BM allows any individual to create an ad-hoc talkgroup by using their as...

Re: Mysterious trouble with Zumspot and Pi-star 1.1

"Pi-Star 1.1"? Pi-Star is a software suite, and the current R-Pi version of Pi-Star is 4.1.6! My diagnostic approach would be to (remember to have the board powered down at start of each step -- don't pull the power cord if possible, use the "sudo shutdown" from a SSH session): R...
