Converting RFX1800 to RFX900 and back

GNU Radio
1

I was looking at the opnbts wiki and found out that I can
convert the RFX1800 to RFX900 using

burn-db-eeprom -A --force -t rfx900

I just wanted to make sure that conversion is safe and
can be reversed before I do anything stupid.
So is there anything like

burn-db-eeprom -A --force -t rfx1800

as well?

Also, I suppose once this is done, there is no need for removing the ISM
filter, since the RFX1800 does not have it.
Is that right?

Thanks

PS: there is a message

ddescribing how to convert rfx900 to rfx1800 and back, but i
currently have an rfx1800 so this does not answer my question.

Hi,

I havent used these boards so I havent looked at the RF components etc
to
answer your second question but my understanding of the burn-db-eeprom
program is that it just updates the frequencies, gain etc that the
daughterboard reports it can handle when the appropriate function is
called.

There should be no problems with (forcing) any (i found at one for the
rfx1800 and rfx900) eeprom data file onto any board. The program just
rewrites the EEPROMS “flash drive” with the data in the file via an I2C
bus.

Performance will be terrible (or gnuradio wont let you set appropriate
values) if the eeprom isnt flashed correctly but theres no reason you
can
just re-flash the EEPROM.

Cheers,

Tim
