Identifying Hotspot

[2E0SEI]

Hi Every One
OLD age and soggy brain cells, off air and radio for a few years, and now playing with stuff Iv had along time forgot how to use update.
Then reading for hours and hours, trying stuff out, then trying to understand every thing.

So question for you brainy lot.

I have a raspberry pi with a hotspot, I got this a few years ago, JUMBO SPOT, I believe it is/was.

1 how would I find out what I have.(it works so its just for my information)
2 As one above would need to know if I need to update firmware. (do I need to?)
3 In pi-star in radio/modem I have always used:

1 STM32-DVM/MMDVM_HS-Rasperry Pi HAT(GPIO)

But thinking I have a Zumspot ????
I tried 2 3 below
2 Zumspot -dual band rasperry pi
3 Zumspot -singal band rasperry pi

both worked?? (CONFUSED)

Then I have always used 434.200000 ?
was thinking of getting a dual band hat, so I used 145.200000 and it worked? (CONFUSED) do I have a dual hat already?
Was looking to update may be raspberry pi and hat?
I have raspberry pi 3plus.
Now I dont know what I have lol. or should I update?

Read what I have wrote. may be I should give up a get 2 bean cans a some wet rope.
So be kind and try to make some sense of my ramblings.

Thanks for any reply help

WOW
Thank you for a very speedy reply.
My brain is working in slow mode so so reading your post and replying as I go.
my hat I got from our main radio shop in the UK, we gave two main suppliers.
Cost me £90.00
Broad colour is green. Cant see any thing on board as offset sticker is covering it.

Plat form
Pi 3 Model B (1GB) - Sony, UK
in pi-star radio info
FW HS_HAT:v1.5.2 DO I need to update firmware?
I have
1 antenna SO simplex?
Pi-star software? I updated as re-imaged my sdcard so set up new on
Pi-Star:4.1.5 / Dashboard: 20210721
OK I dont need new RPi 4

Still confused about dual band hot spot?
This is what I am looking at:£160.00
The ZUMspot RPi Dual Band is an Advanced Radio Module Board.
Paired with a Raspberry Pi and the MMDVM software becomes a small and efficient multi-mode digital hotspot.
1 antenna? white board

Temperature Compensated Crystal Oscillator

Has circuitry to counteract frequency shifts caused by temperature changes. (The next step up is a crystal "oven" -- which has heating elements to bring the crystal up to some design temperature and then hold it at that temp.)
