Greetings to all here

I'm in trouble with my FT-990. Suddenly I notice that cooling fan starts very often even when radio in RX mode. After few days output power decreases to 40-50 W.
I check PA unit current drain and found it 6.5 A at RX mode, it looks like some kind of spurious generation.
If I disconnect cable from TX OUT at RF unit I get about 1,2 A, but I don't know if its normal.

Can anybody help me to sort out the problem?

Thanks in advance

Dmitry

Hello

I'm using RuPay to do PayPal transactions. This is the only way for me since I can't use PayPal directly due I'm in Russia. Check my feedback at www.ebay.com, user id : stranger_tlt
