Re: [Elecraft] KPA100 SWR bridge adjustment 160m 80m

Dear Don, Thanks for your support!! there is a deep and sharp null for all bands except 80 160m, cannot get lower than 1.3 for 80 and 1.8 for 160, I did check the core and it is the large dark gray core. I also removed T4 and did check the solder connections. No difference in results. Maybe

Dear Kevin, Thanks for your reply! I did check the core and it is the large dark gray core. I also removed T4 and did check the solder connections. No difference in results. Maybe asking Elecraft for a new FT50-43? 73 Koert PA1KW Kevin Schmidt wrote: Dear Koert, It probably isn't

Dear Don, Just did check the dummyload with an MFJ analyzer and is working fine on 160m and higher. 73 Koert PA1KW Koert Wilmink wrote: Dear Don, Thanks for your support!! there is a deep and sharp null for all bands except 80 160m, cannot get lower than 1.3 for 80 and 1.8 for 160, I did

Re: [Elecraft] KPA100 SWR bridge adjustment 160m 80m

Dear Koert, It probably isn't the problem, but you might check that the core used for T4 is really an FT50-43. The wrong core might not have enough permeability at the lower frequencies. 73 Kevin w9cf Dear all, Please find my emails to Elecraft support below. Is there maybe somebody with

Re: [Elecraft] KPA100 SWR bridge adjustment 160m 80m

Koert, The absolute minimum voltage found in the C1 null (as observed at TP4) is not as important as the depth of the null. If you cannot achieve a deep and rather sharp null, there is something wrong with either T4 and its associated components or with your dummy load. The actual voltage
