You need to increase the sensitivity a little that toy does not have much power. If you take the top cover off you will see that there are two jumpers. First install one to see if that will be enough. If you still don't get full power install the second one as well for maximum sensitivity and gain.

I have to warn you though, those toys use Rohm IC, this IC is nasty, it creates spurs close to the carrier. It was designed to work in mp3 transmitters going a few meters far with their range. But if you amplify that to substantial power you may start interfering with other services, it can get you in trouble. So my advice to you is get a decent transmitter to drive that amp.
All our transmitters use discrete VCO and PLL. Even our PC based exciters use the same high quality VCO/PLL.
