Re: K3 for POTA

Hi Bill,
I usually call CQ over a period of 15 minutes or so. Then go to another band and maybe come back. 

From here on the CA coast 10-15 spots is about par if the band is open. Running my K3 at 100 watts to a hex-beam up 25 ft, usually pointed due east to cover most of the Atlantic coast. 

Anyway, I wasn’t complaining. I try to get on the air every day and enjoy rag chewing on CW. FT8 holds no joy for me. :-)

73,
Brian, K0DTJ

GM Brian,

How long did you call CQ?  I tried this on 20m a little while ago calling "RBN test K8TE K8TE".  I was spotted 25 times, then 30 minutes later 23 times.  That was with a low (35 ft.) OCF 80m dipole and 100 Watts).  I see about ten CW signals on 20m now in my K4 display.  There were nearly 72K CW QSO's uploaded to ClubLog for the week ending Friday at 2400 UTC.  Yes, much of the activity is short contacts by POTA, SOTA, IOTA, County Hunters, etc.  And yes, FT8 has had a negative effect on VHF and up contesting as noted by KK6MC is a recent contest summary.  When bands are open and CW and SSB can rack up much higher rates.

Way too many of us don't call CQ to "open" bands that too many say are "dead" when FT8 reports -10 and higher (S+N)N ratios.  Big contests increase QSO's in which any period they occur.  That increase comes from a tiny minority of ops.  Sadly, the majority of hams are relatively inactive.  ARRL has begun an initiative to learn why.  Those of us who are active have many opinions.  Frankly, I don't think any of those matter.  That's like asking those who use a gym if the hours work for them.  Really?  Ask those who don't participate if you really want to know the answer.

In the meantime, get/stay active and get on-the-air.  Start with a CQ if you don't find an interesting QSO to join.  And, consider chasing POTA, SOTA, IOTA, counties, etc. in addition to DX'ing and Contesting.  There's still a lot of fun to be had on-the-air.  Even FT8 provides fascinating insights into propagation.

Not out here in W6. The last guy I worked on CW on 6M, 4 years ago, took
three years to send me a card (after I sent him thtre). FT8 is 20 dB
better than SSB and 10 dB better than CW with great ops on both ends. I
work CW and RTTY in HF contests. Am burned out on SSB, thanks to the

I chase grids on 6M, using FT8 for E-skip, MSK144 for meteor scatter,
and Q65 for ionospheric scatter.

Re: SWR

Mark Morin
 

Lou is technically correct that SWR remains constant along the feedline (except due to losses) and that the complex impedance changes with position whenever there is reflected power. Many will argue against this statement but it’s true based on the definition of SWR (ratio of voltage amplitude at a peak position of the standing wave, to voltage amplitude at a minimum point of the standing wave).

Many “SWR” meters don’t actually measure true SWR, but impedance at the point where they are connected, compared to 50 ohms. Since the impedance changes along the line, it’s normal that such an impedance-based meter will give different readings at different locations. Even if it’s not strictly the line SWR, it is still a useful measurement because it reflects (no pun intended) what a transmitter at that point would experience. 

This topic typically provokes debate.

Thanks Bob, Took measurements first with everything out of line and then adding back in with both K3 and MFJ Analyzer.  The main issue seems to occur when the amp is in standby

mode, other changes are minor when adding or removing things

Mike,

You know, SWR is different at different places along your coax so when you see different measurements in different components, that is normal.  This is more obvious as the SWR at the antenna is higher and almost negliable if the antenna is flat.  You can experiment by pulling out the coax that goes into your tuner (I assume goes directly to your antenna) and plugging that into your K3 as an interesting test.  While I wouldn't expect them to be exact, they should be much closer and prove to you that SWR is different at different places up and down your coax.  You could also add a random length of coax to your antenna coax and I'll bet your analyzer gives you two different readings (compairing with and without extra coax).  If you want REALLY good SWR, add 1000" of RG-58 and try 10M...just kidding, because at that point, there won't be much signal left even though your SWR will look great!

I'll leave it to one of the engineers on here to explain why but as an appliance operator, that is what I've observed in practice.  ;-)

Re: SWR

K3 reduces power out when it reads high and lights up high SWR.   Lengths of coax jumpers made only slight difference.  Made up new jumpers first and installed them from rig to amp and amp to tuner.

Complex impedance changes along the coax.  SWR remains constant, except for decreasing due to loss in the transmission line as you move away from the load.
