Bob, I have two DR-605T radios, and both have one pot, VR204, which adjusts the combined voice plus tone levels going to the modulator. It is not possible to adjust the CTCSS tone level independently. However, I padded down the tone levels, upstream of this pot, on both radios to about 600 Hz deviation from more than 1500 Hz before the mod.
The main message here is not about whether a specific brand or model of radio made for the Amateur Radio market will meet commercial specifications; few will be so well-made. The issue is, I think, why don't the majority of radios made for the Amateur Radio market meet the specifications of their manufacturers? I should not have to perform surgery on a new radio, right out of the box, to make it perform within the published specs. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, March 15, 2007 9:13 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Amateur-Grade Radios (Was: Fixed Audio) At 3/15/2007 20:13, you wrote: <snip> Guess I'm good at picking out the "exceptions". Don't recall for sure, but I think the DR-605's CTCSS level is adjustable too. Either way, the one I owned for a year or so before it was stolen didn't have excessive CTCSS deviation. <snip>
