Re: Elecraft Digest, Vol 120, Issue 66

Actually, most of those of my acquaintance, who are concerned about
bandwidth are *extremely* competent, technically, and *do* care. The
real problem is those who can, and will, abuse the bandwidth.

In Canada there is a very wide 6kHz bandwidth limit on all HF bands,
save for 30-meters. The behaviour of VE's is such that, to my knowledge
and that of other VEs with whom I have spoken of this matter, it has
never been a problem. In the US it is a different story and *should* be
of concern.

I have an extra RX window set up to receive signals from VFO B in split mode so I can tell who the last worked station was while I copy the DX with VFO A. With a narrow 400 hz bandwidth and 10 khz span on my P3 I can easily tune from station to station centering his tones in the narrow P3 curser. A 2.7 KHz curser pattern on the P3 would cover up most of what I want to see. I for one would not upgrade my P3 software until this issue is corrected. A narrow 400 Hz curser is necessary for both VFO A and B in RTTY as far as I am concerned.

I noticed that the P3 display showed a wide (+-.75 KHz from center) pulse pattern centered on the frequency I was on. I also noted that there was a strong (XE2, not that it matters) almost 3 KHz down. The P3 pattern matched the CW pulses of that station down band. I wasn't hearing anything but the weak station on the K3 (well done Elecraft).
