Gerry, the option does not come with cells. You will have to install 8 NiMh cells into the pack. I use the highly recommended Sanyo Eneloops in mine. Michael Blake k9...@mac.com <mailto:k9...@icloud.com> > On May 31, 2018, at 4:34 PM, Gerry Hull wrote: > > Here I am

Re: [Elecraft] PA DISS fault and relationship to SWR

Andy, I have seen this too.  My remote tuner will sometimes quit with SWR in the 1.4 : 1 range.  Sometimes it causes a KPA500 SWR Fault and sometimes not.  My GUESS is that it depends on whether the impedance is <50 ohms or >50 ohms.  The SWR does not tell you which. Michael Bl

[Elecraft] K3s SSB generation ?

When transmitting SSBSC is the output from the DSP a SSBSC or DSBSC signal? It is not clear to me if the crystal roofing filter removes the opposite sideband or just cleans up what is left of the opposite sideband coming out of the DSP when transmitting either LSB or USB. Michael Blake k9
