Joe, No hack is necessary. Simply use the "Shift Key Technique" to enter frequencies down to 434.000 MHz. To do this, open the RSS and tab into the RX or TX frequency window. Hold down the shift key, and type in the first three digits. Release the shift key and type in the decimal point. Again hold down the shift key and type in the remaining digits, including all trailing zeroes. Then, tab out of that window. The frequency you entered will appear in the window.
Please understand that the above technique will program the R1225 for out-of-band frequencies, but the RX and TX performance will rapidly deteriorate, the further out of band you go. Expect the RX sensitivity to decrease as you go below 444 MHz, and the TX power amplifier will not be happy- so reduce the power setting. The R1225 does not have a built-in circulator like its high-tier cousins, so there is a risk of burning up the PA with out-of-band operation. Good luck! 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Joe Sent: Tuesday, December 30, 2008 3:14 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] R1225 below 444Mhz?
