Extension of the TX range of the FT-840

Ok guys, I see quite a few people looking for "mods" for this radio, so here's how to get the FT-840 out of the allowed band.

Všetko je jednoduché, pri použití konektora na pine TP2003 sa nemusí nič letovať. Ako zem som použil zelený vodič na štvorpinovom konektore, ktorý je umiestnený blízko TP2003. Je to zem pre RIT a SHIFT. I simply threaded the stripped end of the wire through the connector and reconnected the connector. However, check the diagram to be sure. Then proceed as follows:

1. Remove the lower and upper cover of the radio.
2. Pripoj jumper (spojku) z bodu TP2003 on the ground. This connection is only temporary, during programming. Point TP2003 sa nachádza pri prednom okraji lítiovej batérie.
3. S vypnutým FT-840 súčasne stlač tlačidlá SSB a AM, turn on the station and then release both buttons at the same time.
4. Na displeji sa zobrazí 02-on. Stlač tlačidlo AM to confirm the setting - appears 7.000.00 LSB.
   • Ak sa nezobrazí 02-on, turn the main tuning knob to change the setting.
5. Turn off the station.
6. While turning on the station, hold the buttons at the same time MEM, DOWN a UP.
7. Turn off the power and remove the jumper.

If a problem occurs, load the contents of the backup memory back using the switch backup switch-u podľa manuálu, a potom zopakuj vyššie uvedené kroky.

Now it's up to you.
