@migdelta Sure! Try flecaros@msn.com. But now don't forget to do a full RESET (Power On + M), put your equipment in VHF band and press Band button twice (or three times), by default will be normal VHF (but expanded from 136 ~ 174), next pressing will be UHF trough the VHF stage, and if the combination you chose it's the full band expansion, with a the next BAND button pressing you'll get 118 ~ 136 Mhz. Ther is only one combination with full range Mod.
@migdelta I suggest you don't make several soldering and desoldering over the main board, it's a flexible layer absolutely sensible to heat. I used a Butane gas soldering tool with the lowest temperature adjustment, but be care with the lateral flame. try to get an old notebook (bad off course ;) ) hard disk, break four pins, solder tiny cables to one side (from an IDE flat cable) and this cables over the type bus. With this artifact construct the true table for your rig. 73
In fact, I did nothing to the detector unit, It still is a FM detector but I suppose that with reasonable strong signals the amplitude variations could appears like phase variations I guess, and the detector could decode it clearly with loud volume.
In terms of the range coverage, I don't know the TH-77E, but if you watch my other videos, the uP have a TYPE bus in wich, you can set the range trough W5, R127, R128, R129.
@migdelta If you sense that you lose some sensitivity in the extreme edges, you may solve it re-writing the VFO limits trough the keyboard. The analog voltage for varicaps it's retuned I guess, and now in the very large range the sensitivity turns impressive. 73 Good DX.
@migdelta Please don't forget that if you decide to modify you equipment based on my video you'll do it at your own risk! You'll manipulate extremely small chips and if you damage your radio the responsibility is only yours. Good luck!! 73.
can you give me you MSN or something like that? I already make some modifications, but I still capture the original frequency. =(

Hola amigo.

-Voce tiene que me decir como lo ha hecho esto! Yo tengo la TH-77E.
-You need to tell me how you do that! I have the TH-77E.
-Voce tem que me dizer como é que fez isso! Eu tenho o TH-77E.
