They work better. Now the performance increases are seldom linear with price, so at some point you have to say "good enough", but you generally get what you pay for, and the more expensive radios do deliver more performance of one kind or another (better selectivity, better frequency accuracy, more modes, better IMD performance, lower noise figure, etc, etc). You have to decide what level of performance you need for a given activity and select from radios offering that level of performance. For many people, a PRO-2006 and a Sangean 818 are "good enough".

Our club has purchased one and put it on the air. We have not been able to figure out to get the IDer to ID at some reasonable time limit, such as 5 min. The best we have been able to come up with is an ID every time it transmits. 73 ------------------------------ Date: 10 Dec 1993 19:49:44 GMT From: library.ucla.edu!europa.eng.gtefsd.com!howland.reston.ans.net!math.ohio-state.edu!mane.cgrg.ohio-state.edu!aus1.robins.af.mil!wrdis02.robins.af.mil!gwood@network.ucsd.edu Subject: MANUAL To: ham-equip@ucsd.edu I'M LOOKING FOR TWO MANUALS ONE FOR A BLACK WIDOW THE OTHER I BELIVE IS A LINCOIN BOTH ARE 6MTR AM AND PUT OUT 12WAITS THE LINCOIN WORKS FINE BUT THE BLAC WIDOW I MISSING ONE TUBE AND GOD ONLY LNOWS WHAT IT IS BECAUSE I SURE DONT.

Antenna Specialists carries just what you want in their *police* catalog. It's a "stealth" antenna for undercover work. They have models that exactly emulate the appearance of ordinary auto radio antennas for that vehicle model while actually being high band VHF antennas, and they still work for AM and FM reception too. They include the duplexer. Any AS dealer who supplies police agencies can order you one for your car. Installation can be a little tricky. Note, a center of roof mount will still work better than the cowl mount, but this is better than on-glass or magmount expedients.
