[VHFcontesting] FN55 - Transverter drive control?

Just one more approach....if you can source ordinary resistors at a good price you can build your own power attenuators for 28 MHz quite easily. It looks like 100 1 watt resistors would be around $30 from Digi-key, maybe 1/10 of that from Chinese vendors on Ebay.  Each resistor is probably somewhat inductive at 28 MHz, but with enough in parallel the inductance is divided by the number of resistors and becomes pretty much negligible.  Here's a 100 W (or so) dummy load using that approach - the SWR is great on 10m, but not so good on 6m:

Occasionally I think about converting it into an attenuator, but haven't gotten around to it yet.
