UNIDEN HR2510 / UNIDEN 2830 / President LINCOLN
Used this radio and a couple of other 'President Lincoln' in the years 1997-2002. This 'President' comes in some different models,- I used them al, the 'Lincoln', The Uniden 2830 and the 'HR2510' - At one time i owned two 'HR2510' at the same time!. On this page i describe som great mods i made to the radio, most for fun, but some is also verry useful. In al those years i had no problems with any of these radios (Total of 4 different radios).

This is my 'Last' FreeBand radio,- from this one i only used 'Ham-Radios' - My FreeBand days ended in 2003 when i finaly got my Ham-Ticket and got my license as SM2YER.
