The main legal restriction signals from the control unit are grouped on connector 10 on the RF board. The connector carries three logic signals: TXI, WRC, and PD, their descriptions being as follows:
TXI TX Inhibit - out of amateur band.
WRC TX Inhibit - out of WARC band
PD Power down (ie, reduction) on 28MHz (for USA)

The behaviour of these lines may vary depending on the serial number and country of purchase.
Additional transmitter inhibit signals are derived from the receiver roofing-filter selection logic, on the RF board itself; these being used to prevent transmission in the range 0.15 to 1.6MHz, and to apply additional restrictions in regions where not all WARC bands are allocated. For M-type transceivers, regional WARC band restrictions can be removed by unplugging the white link-wire on the RF board (see the user manual, p22). Other versions do not have the WARC band restriction components fitted, and so transmit on all amateur bands without modification. When configured for full amateur use, the transmitter frequency coverage is as follows:
1.6 - 2, 3 - 4, 6.9 - 7.5, 10 - 10.5, 13.9 - 15, 18 - 19, 20.9 - 22, 24 - 25, 27.9 - 30 MHz.
Note that that these ranges already give considerable coverage outside of the amateur bands, and place the onus on the operator to avoid unallocated frequencies. If you require additional coverage, removing the plug from connector 10 enables transmission at full power over the complete HF range from 1.6

El articulista dice que solo basta desconectar el plug del conector 10 de la tarjeta de RF para tener trasmisión a full potencia en todo el rango de HF desde los 1.6 Mhz.

Recuerde que hacer esto está prohibido en la mayoria de los paises.

Hola

Mas claro imposible.


Ten en cuenta lo que te dice el amigo en cuanto al aspecto legal, ademas recuerda tendras full power que, creo, excede por mucho la potencia admisible de los 27 MHz.

Suerte.

Hay que desenchufar el cablecito marron y listo.-

mi ta430s no resive

Amigo Elkin, debes iniciar una nueva pregunta, ademas trata de poner los datos que puedas, cuándo fué que tuvo la falla, si recibe muy bajo, aunque sea las AM cercanas en MW, sila transmisión está normal, si has intentado repararlo y cuanta cosa aporte para orientar a los amigos.
Te esperamos.
