I am using a Flex 6700 with WSJT... I now want to use my QSKIIc sequencer for QRO EME... I set up a virtual com port and set it for PTT RTS/DTR and set WSJT to PTT RTS and it seems to command the PTT in the Flex OK but any ideas of how to get a command to the PTT input port on the sequencer???
Tnx, bc AH0U

 Hello,

I have noticed as well. A friend told me some operators may use two WSJT-X or similar programs to run them together, to make twice as many contacts during a contest.  I think it just makes them twice as slow. Maybe this is what happened in your case.

No, the mix number is NOT "the" spec, it is only part of the spec. The cables in the link only go through the core once, which causes the effectiveness of the choke to peak around 150MHz. If you need a choke that works on the HF bands, you need multiple turns through Fair-Rite #31 material.

See k9yc.com/RFI-Ham.pdf for a tutorial on how chokes work.

http://k9yc.com/KillingReceiveNoise.pdf is a tutorial on finding and killing RX noise, and the chokes described in it work equally well for RF pickup on cables.

Plus with good cables the products would pass without ferrites.
Passing FCC Rules does not mean a product won't produce noise that we hear on the MF and HF bands because the tests are not meaningful -- they don't expose the design/construction errors that put RF noise on interconnecting cables. The most common error is "The Pin One Problem," whereby the cable shield goes through the shielding enclosure without being bonded to it.

However
in ham radio apps, the ferrites are a good idea due to the RF
environment.

Ferrites are generally needed because 99.9% of products are built with "Pin One Problems."

I do agree with the observation that many (most?) commercially available cables are of poor quality, and without sacrificing one by cutting it open, there's no easy way to evaluate them.

locked Re: Question about SNR reports

Jim Brown
 

For most hams, this is NOT true below 2M, because our limitation is noise from all sorts of electronic sources in our homes and neighbor homes. A preamp improves signal to noise ONLY when the noise from the antenna is close to or below the level of noise in the RX input stage.

My friend AG6EE often makes expeditions for rare grids in the US state of NV, and he finds very isolated locations that are electrically very quiet. He DOES, of course, use a preamp, and he regularly hears 10-20 dB better than stations calling him.

My QTH in the Santa Cruz mountains is sometimes fairly quiet, but I have neighbors within 100-300m, and sometimes they make noise. I run legal limit (1.5kW) to very good antennas on 160 to work EU and on 6M. WSJT-X regularly gives signal reports 10-15 dB better than I receive from the other station, and very often, stations that are -10 here don't copy me.

Recently I've been running 50W on 60M, with the same result.

HI Tom,

there should be no surprises from your test observations, on the contrary if the pre-amps had changed the received noise power relative to the received signal strength you should might then be surprised. Receive pre-amps are useful when located at the far end of a lossy feeder system that might reduce the weakest signal levels below the front-end noise floor of your receiver.

Mark Lunday, WD4ELG

Hi Mark,

there are many ways to form signal strength reports, each has limitations.

1) S-meter, these are roughly relative to absolute received signal strength but do not account for noise contributions,

2) absolute logarithmic signal power, usually in dBm, which are accurate measurements of received signal strength but are only meaningful alongside details of the aerial system used, or if used for comparative measurements,

3) signal to noise ratio, which accurately measure the power of a received signal relative to the received noise power, so are an accurate measure of signal readability,

4) signal to noise+interference ratio, similar to SNR (3) but accounts for interfering co-channel interference as part of the noise power. Note this is not necessarily relevant with narrow band modes like FT8/FT4 where advanced filtering eliminates the impact of interfering signals.

WSJT-X uses (3) SNR with the noise power estimated across a 2500 Hz bandwidth. It attempts to find the true noise power without contribution from interfering signals, although this is not easy to do accurately.

So to answer your question, SNR reports are often not reciprocal because of various factors. One station may have a more or less radiated power, another station may have a higher or lower noise level, yet another may be using a narrower than 2500 Hz bandwidth receiver that distorts the SNR measurement. None of this is exact science, the numbers are at best estimates. We feel that SNR is the most useful way of recording signal strengths.

BTW the next release of WSJT-X has an improved noise measurement algorithm for FT8/FT4 that measures the noise floor far better in the presence of strong signals. This means that SNR figures with large positive values will be given for the strongest signals, rather than the current situation where they tend to saturate at about the +20 dB range making their value falsely low.
