Personal Best Distance, SSB Phone #ubitx

EI_Frank
 

So what's your personal best distance on SSB Phone.
I'll kick off with a meagre 380 km's (236 miles). With an End Fed half wave wire on 40m with a uBitx.
Who's next. ?

On 6M K9ppy and W4IMD using HB portable rig at 820mW. into the
4 element beam at 33ft.  

For HF:
For 5W using my Argonaut 505 on 40m the best was SV54rwu from W1 country.
For the Slopbucket 20, DL5ARH
These two using LNR EF-quad at 30ft.

For the KNQ7A (40M) VK3 foundation station while mobile (8ft centerloaded whip).
That radio does about 7-8W  at 13.8V.

For 10m during the last solar minimum all of South America, the carib islands,
Falklands and Antartica all using 4W SSB HB into one of two antennas the
PAR EF40/20/10  and the K6STI 10M loop with the top 20ft up.  That was
over a 5 month period.   I credit the K6STI 10M loop a 73" wide by 146" high
rectangle for the better part of all that as it was aimed to favor South America.
The par EF40/20/10 as set up then favored east west paths.

Antennas that are oriented in the desired direction and high enough to
be effective seem to make a difference.

New Zealand, ssb 3w qrp with the Spanish ILER20. I logged that as an ordinary qso. I was not in the States of course... But in Italy. New Zealand is exactly on the other side of planet earth from my qth. Just let me say that if you hear anything around s9 or more if you use a qrp you can have a qso, of course it will be more difficult during a pile up. So give up FT8 and come back to cw-ssb!

First SSB contact with new uBITX was with JE6EHP on 20m with an end-fed random wire. Nice long chat. Well over 8,000 Km. -Don

Can anyone send me a pic of uBITX manager with the loaded information for a ver 3. The uBITX is loaded with 1.097 and the display is loaded. I’m unfamiliar with the information process. I have learned so much on this project and want to continue to do so. I read everything that is posted here. It is truly a learning experience. 73’s KN4LPH

 

I worked a station in Antartica from my QTH in Oregon, a distance of 10,455 miles, on a Bitx17A running 8 watts into a EFHW antenna. I have the QSL card to prove it!

JC  Keep that Bitx17A .. it seems there will not be many more kits made.

BTW if you can get the 9 turn fine tuning air variable  out of an old UHF TV receiver ( typically can be made to tune 3-30pf  and less over the full 9 turns by cutting comps out and wiring the plates in parallel) you may be able to produce a non thermally moving VFO for that beast.  Australia killed off the Analogue network a while back and I had the opp. to examine the internals of some of these.

About 2600km on 80m - with a half-collapsed wire antenna

But otherwise many contacts between VK and USA or Europe with 5w.  Eg

Don:

Your AGC circuit calls for RF-out to go to K1 pin 12, and RF-in to K3 pin 14. I have scanned the version 4 schematic, and I cannot find anything labeled as K1 or K3. I could guess, but I don’t want to make a mistake and cause any damage. Can you please clarify?

David,

I pulled a copy of the V4 schematic and guess what.  They are marked, and at the bottom
of the page and K1 is extreme left and k3 is extreme right.  So no need to guess.

K3 is next to the antenna connector and it says so right next to it. The writing is
between the relay and the antenna pin plug.

K1 is on the opposing side next to the power connector and it is also labeled!

I wear glasses to read (+1.6) and if I can see that without them then one hasn't looked closely.

David, by the way the topic is  "Personal Best Distance, SSB Phone #ubitx"

Why did you post about not finding things about the schematic here???????

Allison

 

Allison,

 

Well my eyesight is not as good as it used to be. However, the ND6T schematic did not identify K1 and K2 as relays so I was not sure where to look. Plus, the “K” for K1 on my board was obliterated by being screened over a hole so all I can read is “1”. Regardless, thanks for pointing me in the right direction.

Sorry, I was trying to connect with Don specifically as I was instructed by Kees, but I didn’t have his email. His name led the post so I hoped he would see it and respond.

Look for his posting and do a private thing (down to the right).
He may or may not respond at his option.

David,
I don't spend much time on line but my email is good on QRZ (yours isn't posted there) and on my web site, too! I try to check my mail at least once a day.
Anyway, if you put the AGC or the RF gain control in backward it is no big deal. Maybe a couple of dB difference.
Like in wiring the encoder, if you find that you have it backward then just reverse it. Unlike wiring up a whole new circuit, this is just two connections.
Don't worry, just have fun! -Don

 

Thanks!
