About any Ham vintage rig made in last 15 years is not good for a repeater. On the receiver the clue is it has broad band receive. Some receivers have some tuning geared to the rcv freq, but very little. It is radically different than a rcvr with helical front end filter that has to be tuned if moving more couple MHz.
The Ham repeaters are also a problem. The clue here is just connect a computer and set freq to one at DC to light range...well like for VHF, 134-174 MHz. The front ends must be designed to accept this and they do no matter what your op freq is. The other problem is the TX spurious emissions of only down 60 db. This noise then requires a 6 cavity duplexer or 100 db notch to make work well. Sure it works today, but what about next week when the weather changes. A good TX like a Micor or GE MII will have this at 80+ db range. Now a real good one like the Mot MSF5000 at 120 db. The type acceptance thing is another, but important issue. The type acceptance issue is why certain rigs are not allowed in certain places. This is one. 73, ron, n9ee/r >From: [EMAIL PROTECTED] >Date: 2008/03/24 Mon PM 09:55:03 CDT >To: Repeater-Builder@yahoogroups.com >Subject: RE: [Repeater-Builder] Using Alinco DR-605 Dual Band Mobiles for >Repeater > >At 3/24/2008 06:57, you wrote: > >>Front end is too broad > >Actually, the front-end of the DR-605 is one of the narrowest of the >current-production radios (I know, the 605 is no longer current production >but it's only been a couple of years). > >> and not legal for GMRS...... > >Quite true, which makes the above a moot point w.r.t. repeater >[EMAIL PROTECTED]@[] 9318:19:54 i 9491692 216.252.122.217 [EMAIL PROTECTED]@[] >918:19:54 d 9491691 [EMAIL PROTECTED] S 0 pr=groups-email-ff-m >id=2275891-m1655918:19:54 d 9491691 [EMAIL PROTECTED] S 0 pr=groups-email-ff-m >id=2275891-m1655918:19:54 d 9491691 [EMAIL PROTECTED] S 0 pr=groups-email-ff-m >id=2275891-m1655918:19:54 d 9491691 Yuedragpan class="left"> > Messages in this topic (20) >Reply (via web post) | Start a new topic > Messages | Files > | Photos | Links | Members > > > > Change settings via the Web (Yahoo!
