I
tried several new coils. 60 turns of #22 will give you a very robust coil
but it is hard to get all the windings on the coil form.
Wind
tight when using number 22 wire, there is not very much room on the center
coil form. 
47
turns of #24 seems to be about right, easy to wind and the wire size is
easier to manage. Theoretically the #24 wire is larger than the original
winding so you should have a higher Q.
This coil can be adjusted slightly by compressing or spreading the windings to achieve best match.
Secure
the windings at each end by going through the coil form and then solder
Use the original holes.

or use your reflected meter and a test setup as shown on the first page
of this series. If you use a reflected power meter don't get freaked out
on the SWR just tune for min reflected power. There is very little line
loss so the SWR is not a factor. Shoot for 3 or 2 to one or go crazy and
go for 1 to 1. Every coil here was easily tuned to 1.5 to 1.
For a 1/2 second quick radiation test test I used a florescent light bulb.
Notice that no one is holding the bulb, and the photo was taken from the
other side of the room. The bulb is suspending from the ceiling with a piece
of cord. NOTE: we are probably exceeding the (MPE) Maximum Permissible Exposure
radiation minimum standards- conduct this test at your own risk,run low
power, stand 30 feet feet away. During all testing the antenna is mounted
on a BNC mount on top of a aluminum chassis to simulate the ground plane
of the radio.
Stock
up on different wattage's. Great for night recon and emergency lighting
course you have to transmit to see then of course there is the MPE so
maybe you should just use a MX-99/U **
