Add some more wire, even if you cannot get the additional wire stretched 
out straight or high off the ground, until the total wire length is 
closer to a full quarter wavelength long.

Or you could extend the tuning range of your 227. Which component in the 
tuner is set to maximum? If it is a capacitor, add some parallel 
capacitance to it. If it is an inductor, add some series inductance.

If you invest in a tuner that can handle higher power, it will also 
likely be more efficient at the power level you are presently running, 
and when you do get an amplifier someday, you won't be wishing you had 
bought the bigger tuner.

I really like my TT 238 except for the dial string problems I have had 
with it. Seems like they can be had for roughly  $300 plus or minus, 
depending on condition.

You'll might have more fun scrounging for parts at hamfests and building 
your own. I suggest the 238 as a model, basically an L network with 
series inductance and shunt  capacitance switchable to either input or 
output side. You can use clip leads (good ones. Build them yourself from 
Mueller, Pomona or other quality alligator clips. Don't waist money on 
cheapo clip leads) instead of a switch, and it doesn't really need to be 
in a box.
