I have been offered a solution to my amplifier woes. The mast problem has been addressed in a temporary fashion to prevent further damage while waiting for the weather to improve. Meanwhile I want to
Using the -10 dBm transverter output is not an option (even if I could amplify it 20 dB). Can you please tell the list why not? In my radio (FT-2000) the transverter output is only available (and PA
I have several replies already and I understand there are issues with using the ALC input as proposed. I am scratching that idea. One responder gave me what looks like the solution. I didn't want to
I've never done this myself but I've heard of people using a run of high LOSS feedline between the two to act as an attenuater. -- Mike Urich KA5CVH http://ka5cvh.com PIO Harris County ARES STX: (A)P

This is a good suggestion. I've used RG-174 to build attenuators for a long time (I found a reel of it at a local surplus store). RG-174 is small and easy to work with. It will handle a hundred watts

Hi All. I've started down this road (my radios with dedicated transverter connections don't put out out enough power from the transverter ports to run the transverters I want to use, plus I have a ra
High power attenuators are expensive and I don't like to be generating 100W on the IF frequency. I've never done this myself but I've heard of people using a run of high LOSS feedline between the two

Paul 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 aroun

If you can use the radios power control to reduce output to the 20-25W range, I've found this to be a simple, cheap and effective solution. I use one of these on a IC-706. I dial down the power and u

Paul's current plan is derived from the approach that I have used in the past that worked very well for 10M IF use. I started with a Vectronics DL300M dummy load, HRO currently lists them at $50. The
