Hi, really nice work with this new expansion board for up4dar!

Can you please answer two questions to me?
- How do you program/change the frequencies?
- If you install this board extension, will you be able to use the external radio too?

Thank you for the answers and keep up the work.

In the german part of this forum Denis made some explanations for the repeater mode with the RMU installed (RMU V2.0 auf der HamRadio 2014 vorgestellt). In that thread he mentioned, that the RMU can be disabled and enabled - IMHO there will be a new firmware with settings to switch the RMU on/off, set frequency and so on.

Looks Great Dennis

But i have a question about the 3.0v to 3.3v is that to do by myself .
Because sending to your service cost me more.
and is there a manual whit the module .

Hi,

if you have a look on the electrical schematic you will see on the first page you will see the 3.0V LDO. This is the old voltage for a radio module, which was never available for the public.
The current Radio Module for UP4dAR, RMU V2.0 needs 3.3V in order to transmit with 30mW. For this you have to remove the LDO and short cut the Input-pad with the output-pad.

I do not know if you can do it by your own....

My recommendation is to send it to us.

hi, thank you for guiding me to the german part of the forum, unfortunately i dont speak german :(
I tried google translator and if i understand corectly, then:
- in hotspot mode the UP4DAR works fully through RMU
- in repeater mode RMU works as RX and external radio as TX
- if i disable the RMU, which i don't know how atm ;-) , everything work like there is no RMU?
- there is planned new firmware version with RMU support to fully operate frequencies, PWR?, disable/enable the RMU
so there goes my additional questions:
- how does the UP4DAR works in modem mode with RMU installed?

Thank you for your time!

Hi Libor,

I do not know, why you have problems with PayPal. I had a look into the settings. The Czech Republic is in the PayPal white list. So, it should work. If not, I have a work around for you. Place a normal order with the payment method "Überweisung" and send the invoice amount PLUS 5EUR directly via PayPal on your usual way to "info@bederov.de".

Hi Denis, my deepest apology.
As usual the problem was on my side. This transaction required different settings of my credit card it seems, which is strange because i use paypal on ebay quite often without any issues and even last transaction was few days ago too...
Anyway, thanks for help, the transaction was done normaly now and iam looking forward for the package :-)

I just installed the RMU v2.0 board, and I had the same question, on how to program the frequencies.

Well, I just updated the firmware with P.0.02.23.bin, and voila, the frequencies could be adjusted via the buttons on the UP4DAR.

Just update you UP4DAR and you are ready to roll!!

Re: RMU

Denis and myself wrote it some times,

to run the rmu V 2.0 you need both Softwares:
the S (version 37e) and the P (version 23);

and, yes, with a build in rmu you can also use an external TRX in every mode,
but therefore you have to disable the rmu in the menue.
