Hi Paul, VLF I'm checking your description of audio transformers in use at your receiver and making my wish list for the three kings ;-) Would you please confirm some details? As you mentioned earlier: >> For isolation, A262A6E at the output of the rx's line driver and A262A7E at >> the house end. >From datasheets at Farnell, A262A6E is a 150:150 Ohm transformer and A262A7E >is a 600:600 Ohm Is that correct ? There is a metal screening housing for the A262 transformers. Is it needed or recommended ? The "shield" pin in the transformer can be left floating or connected to circuit ground? Assume you are using twisted pair CAT5 cable to send the signal from Rx to house, right ? Do you use the other pairs to provide power supply ? 73 de Luis EA5DOM |
