Hi, it could still be a modulation related issue. Since the license is now installed, you should be able to test each of the following init. strings, one at a time: --- AT &F W1 +ER=1; +DR=1; +MS=V92,0 AT &F W1 +ER=1; +DR=1; +MS=V92,1 AT &F W1 +ER=1; +DR=1; +MS=V90,0 AT &F W1 +ER=1; +DR=1; +MS=V90,1 AT &F W1 +ER=1; +DR=1; +MS=V34,0 AT &F W1 +ER=1; +DR=1; +MS=V34,1 AT &F W1 +ER=1; +DR=1; +MS=V32B,0 AT &F W1 +ER=1; +DR=1; +MS=V32B,1 AT &F W1 +ER=1; +DR=1; +MS=V32,0 AT &F W1 +ER=1; +DR=1; +MS=V32,1 --- Hopefully one of them will solve the problem.
