HS Hat not working properly
Posted: Sun Feb 21, 2021 6:31 pm
Hi all,
Sorry for the generic title but I don't know what is the problem
I have a Raspberry PI Zero W with the latest Pistar OS.
The RPI works fine and I can access the dashboard Pistar and also by SSH for command shell.
I bought a separate kit MMDVN hat from China (Aliexpress) an MMDVN_HS hat with FW 1.4.6 that unfortunately (also stated by other buyers) won't update its version to recent ones. I tried to update with the shell command but after the update, the display shows CLOSE, then when I reboot it comes back with the same 1.4.6 version.
The Oled display works perfectly ,showing also information such as my call sign and the big MMDVM as screensaver.
I set up YSF on Pistar to use with my Yaesu FT-3D just clicking the X sign.
I set up as starting reflector, the PARROT so to hear my messages back. Sometimes it connects to my Yaesu but not all the time.
When I change the reflector (link) on the admin page, I see that the modem transmit a signal to the frequency.
Steps I do:
I Switch on the device.The RPI boots up and run all the code.After 1 or 2 minutes the MMDVM word appears on the OLED. The hat has some leds switched on. There is one green led on the right side with fix green light. while beside there is flashing red led light, approx 2 flash per second.
I connect via browser to the pistar dashboard.
On the dashboard section I see this:
-Gateway activity:empty
-RF activity empty
-Modes enabled YSF in green, the rest in red
-Network status: YSF net
[Admin page]
Radio info section (left)
Trx: empty
TX and RX the frequency in use.
FW: HS_HAT: 1.46TCXO: 14.7456 Mhz
YSF Network ZZ Parrot
[On my radio]
I click on X on my Yaesu FT-3DR to connect to YSF and nothing happens.
[On the admin page]
Under Reflector, I click on Request Change having the same reflector as parrot. But this time, what happens, in the radio info TRX I can see TRX: Listening (in green colour).
I click X on the radio and nothing happens. But, if I switch off the radio and turn on again, then I click on the X, it connects.
But then when I transmit I don't see any activity in the dashboard and neither I get the message back from the Parrot.
If I change the reflector from the Admin page, it shows the changes into my radio but I cannot change anything from my radio.
I tried also to change the TX and RX offset from various range but nothing has changed.
I watched videos on Youtube and it seems straightforward, so I might speculate that the HS HAt might be a rip off and it doesn't work. Before purchasing maybe another one from another seller, I was wondering if there is some troubleshootings or test to do, cause the hat shows some life activity as explained before. Also it happend on several occasion I could hear ham operators while connected to a reflector. So after all it might not be to bin it.
Thanks in advance
