Cary, I looked on Yeasu's web page and found the "vx-5r" which has a EXTERNAL mic jack. If thie vx-5 has it then this may be right up your alley. This will let you plug the keyer strait into your HT and will key it up for you and every thing. I have discussed this wish some VE's in my area and some others and am going to try and get a local VHF code pratice group going.If you build this, email me at "
KD5MSY@Yahoo.com" and let me know how it turns out. I am studing for the code test as well, altho it sounds like your farther ahead than I am "Just started". I am going to experiment and see if i can put a speaker in it and use it as a pratice osocilator off the air. From "what I have been told", dont hold me to it, you can pratice on any of the bands that you have rights to such as 6mtrs and up, if you have a tech ticket, "sounds kinda funny tho"
Like i said let me know if this helps out and if it works. Im going to try and build mine this weekend i will post again if it works...
