222. [Amps] HF 30 dB Coupler (score: 1)

Looking for an HF (3-30 MHz) Coupler for rf measurements. HB or commercial will do. Accuracy is not important but flatness would be a concern. 30dB port would do. Any suggestions ? Tnx, Dick, W1KSZ _

Unfortunately, the link to the Power supply is a dead end. It's a PS--2500A, made by Watts unlimited. They seem to no longer be with us. 73, Dick, W1KSZ ______________________________________________

The QEX article on his supply does not seem to be available for download on the ARRL site. It's the February 1991 issue. Anyone know where I can find it ? Tnx, Dick, W1KSZ ___________________________
