Hi,
If I verify that exactly, then I have another one that in uhf I cannot achieve that transmits in hotspot mode in uhf, I don't know if this problem has happened to someone. Do you say that in the 200mhz band in rx and tx it has the same range? and what power does it offer?
thanks

HI.MY BAOFEN DM-1801 IN TX WORK:

136000 to 172000 - vhf
381000 to 500000 - uhf


does not work at 200 mhz, is this so? Can someone make it work in that band correctly? :cry:

Did you turned "Band Limits" off, in the Options ?

Cheers.

It has installed the last fw dated 04/18/20 where the frequency expansion is, as it is in beta, I am interested in trying and seeing what errors can be corrected.

Sorry but I don't get the question.
If Band Limits is ON (default setting), the 1.5m band is : 222 .. 225MHz

ok,
With which version of fw do you manage to transmit in that band? Could you pass me the link or the file for 1801? since with the fw dated 04/18 I could not make it transmit.
