Re: [Elecraft] KBPF3A < TT Jupiter on Broadcast Band

Thanks, Frank. That's interesting because the shield is usually grounded. I guess this means I'm muting the Jupiter speaker when I connect the K3s because I'm grounding the floating Jupiter speaker circuit to the K3s ground. 73 de Carl, N8VZ Sent from my iPhone > On Oct 21, 2015, at 6:29

Re: [Elecraft] KBPF3A < TT Jupiter on Broadcast Band

Per the manual the 538 Jupiter uses a floating audio output circuit for the speaker. Therefore, one can not ground one side of the speaker line. 73 Bob, K4TAX On 10/21/2015 10:00 AM, Carl Jón Denbow wrote: Thanks, Frank. That's interesting because the shield is usually grounded. I guess

[Elecraft] KBPF3A < TT Jupiter on Broadcast Band

I recently installed a KBPF3A in the sub receiver. I've been surprised to discover on direct A/B comparisons using the same antenna that my old TT Jupiter is much more sensitive on the broadcast band. A station that comes in at S-6 on the Jupiter is maybe an S-2 on the K3s. This is very

Re: [Elecraft] KBPF3A < TT Jupiter on Broadcast Band

There is a high pass filter in the K3 to protect the t/r switch. It is in the circuit to the main antenna input. To listen to the bc band you should use the rx antenna input which is after the h/p filter. Vic 4X6GP/K2VCO Sent from my phone > On Oct 21, 2015, at 1:36, Carl Jón Denbow
