Since your listening and counting I 'm voting. I had exactly the experience Bob had. Couldn't transmit, then when I thought I had it all figured out (4 tries later) in my haste I transmitted on the DX frequency :-( (mea culpa). I believe there would be no problem if the sub RX is installed but under my current cx's it is very cumbersome. On the other hand I see Wayne's point IF the sub RX is available. My vote make it an op option. 73, Howard..K2HK Lyle wrote: The changes came about as a result of careful deliberation based on input from customers, followed by field testing and evaluation of that feedback.

It doesn't matter whether you have a subrx or not. You still use VFO B
to scan a pileup -- you just can't hear both QRGs at the same time. Howard Klein wrote: > Since your listening and counting I 'm voting. I had exactly the > experience Bob had.

The sub-rx document says your loose 3db of signal in the main rx when switching in the sub rx when sharing the main antenna.
For really weak ones, you'll probably want to have the sub-rx off unless you have a separate antenna for the sub-rx. Brian/K3KO

The signal (including received noise) from the antenna is reduced by 3 dB when sharing. If you can still hear band noise from the antenna, you are only losing 3 dB overall gain, not S/N. If AGC is activated, it is reducing gain so the splitter loss is inconsequential. Only if the band is so quiet that you don't hear band noise when you connect the antenna do you risk degrading S/N by up to 3 dB. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Vic, I missed that. That's a bummer for me. When chasing a dx station in a pile up I would like to hear the dx and scan the frequencies looking for the station that is currently working him and be able to quickly transmit on that frequency. My reasoning changes some but my vote remains the same 73.

SSB OPERATIONAL test opinion-- All tests done with max use of all controls to give best sig... so each rig was adjusted differently but to the best function I could obtain for each rig: First test is on a very weak ssb sig with qsb (just barely readable): 9= fully readable for a good contest exchange, ng for rag chew. DNR slow on uptake (a fraction of time before DNR kicked in when the sig first comes on, but after that, very readable with "pinched" audio range). DNR used with Contour which boosted audio output and increased copy. Without DNR, wider audio but reduced readability and no delay. "u-Tune" always on at center setting. 3= ok for contest, ng rag chew. K3 had to have a discernable level of more band noises to give same readabilty, and with NR on, audio is also decidedly "pinched." NB on mid-range; NR made copy discernably worse at all settings, some more than others. 1= Just not as sensitive, about 80% where other two were 90%; using NB at 5H worked better, NR no help at all, so was kept off. Listening included lots of "live band" noise to go with lesser signal. When "live band" noise went down (as tho band is going out), the desired sig was more readable proportionally --readable beyond what one would expect. As on CW, the ONE delivered a more pleasant sounding sig than the other two, but only when the sig built up to move the S meter; otherwise, I missed more % of copy. Weak sig sum... 9 most comfortable to listen to, but 3 very close behind. 1 got nice only with stronger sigs. Lightning on horizon and other Noises: 9= "Pinched audio" is there, but the punch of the static crashes were bearable. "u-Tune" and DNR and Contour on. 3=Static crashes caused a kind of pumping with NB and NR on and adjusted to damp the crashes (AGC on fast really was uncomfortable; slow, more bearable). NB alone was best for readability, but the crashes were definitely worse in sharp peaks of noise. Higher pitch band noise than other two, ORION 1 bass helped somewhat, see below. 1= More bass made noise more bearable. Used NB 5H; but switching the NR1 on with this vy weak sig just cut the rcvr output to zero. With only NB 5H, bass crashes hurt ears less than 9 and K3. However, total sig readability was not as good, and in fact, the reallyweak sig was discernable but not readable in QSB nulls (not as gud as other two). Overall SSB usage: The FT9000d was the SSB rig I wanted to listen to for weak sigs on 20m SSB. K3 was a close second, but the K3 will spoil u with its superior CW rcvr and leave you wanting on SSBdue to the contrast with CW if nothing else. Strong sigs sounded more natural and pleasant on the Orion One where the strong sig overcame band noise and lightning static. IF I HAD TO KEEP ONLY ONE: it would be the 9000d because I do mostly SSB and I REALLY enjoy all the knobs and especially the reasonably functional bandscope. Using the K3 after the 9000 made me search the k3 dial for more info. If I did CW mostly, I would try to add more visuals to the K3 via after market gagets and use only the K3 because it is a CW dream machine. Overall, for this appliance operator speaking, the FT9000d is just plain more fun, looking at it, touching it, and using it. 73, end of this opinion stuff. PS: Tnx to DF0HQ whose CQ contest calls provided over 4 hours of perfectly consistent sig levels--weak with QSB, and thanks too to the weather for the correctly-distant lightning static. FT-9000d just in from factory; K3 just back from factory; and ORION ONE is old and using version 1.373b5 (sure wish I cudda included a brand new O TWO).
