<font face="Verdana, Arial" size="2">What quick release hub is everyone using</font>


Piece of cake and it all bolts right up. Using LTB Motorsports as an example (Louis haunts the IT Forums as well):

Momo Monte Carlo Steering wheel, $143 new, http://www.ltbmotorsport.com/montecarlo.html

Momo hub kit, $48 (http://www.ltbmotorsport.com/hubkit.html)

Quick Release hub. I have the Smart Racing one (http://smartracing.net/ProdCat/Drive...20Comforts.htm, part number 722100, $220) but it appears Louis is offering one that looks just like it for $140, http://www.ltbmotorsport.com/dilquicrelhu.html

(Optional) Momo steering wheel spacer, $22, http://www.ltbmotorsport.com/momsteerwhee.html

Steering wheel stuff, $353 total. I use this setup and it works great:

<font face="Verdana, Arial" size="2">I also want to move from my 'Push To Talk' (PTT) button, to a horn actuated setup...Is it as simple as wiring up a new steering wheel with that capability by taking apart the PTT switch?</font>


Depends on your radio. Some radios open the mic circuit by grounding to a common ground, some work by closing a mic circuit loop. You need to get with the manufacturer of your radio to find out for sure.

However, I suggest against doing it as you describe. Even if it works, your radios will be very sensitive to voltage variances, and any additional resistance could cause noise problems.

What kind of PTT are you using now? I have a home-grown VHF radio system. I'm using a modified David Clark PTT switch originally sold for small aircraft. Also works great.
