Hi fellow hams/contest OP's
I just want to let you know that PI4CC is ready to bring there high
power bandpass filters pcb's available for the ham community.
This is hobby project and you can build a good bandpass filter your self!
We don't claim really high power, but its calculated for 1kW key down
and we tested them 15 min key down with the output of a Acom1000 without
any issue.
During a 24 hour contest in SSB and CW its works great and weak signals
near a second harmonic (2Kc) could be easy copied.
It has better numbers as 4O3A, DG0SA, VA6AM.
Have a look at https://www.pi4cc.nl/tech-info/hp-filter/ for more info
and details.
We are is the stage of make an order for the pcb's, but its difficult to
get the correct amount.
