Its for the Real time clock. its not needed for now. if someone implements it in the firmware then it could be used.

hi guys,
what is the battery holder for on the nextion display ??
something we need ?

Hi Again.

Would folks prefer the Pot to adgjust the ACG or the Jumpers as per Kees' boards?

I am in 2 minds about it,,,

I was wondering how close those fires were.  The rule here if if you smell the smoke
its too close.  Take care.  Keep building!

Re: any tips for debugging RFI issue? #ubitx-help

 

Hi Allison,

I need to redeploy that antenna, I have the feed point at the same level as the far end and the wrong coax on it, so I know it's my fault it doesn't perform any better than it does. I threw it up in the air about 5 years ago and am just too lazy to take it down and do it right, I'm too busy building radios:-). This fall when the forest fire smoke clears I'll do it.

HI Again,
Just PCB boards. I am still designing them, and awaiting a new callsign too, so, I am hopin in the next week or so to get all my current board designs finalised and then place and order.

One more pic of the VK4PLN ND6T AGC board:

Hello, do you know if you have possibly shipped my unit?

Nick, would like to obtain 2-3 of your AGC PCB boards. If you are
planning a kit with parts, I can wait for that too. - Rich WB2GXM

HI Kees K5BCQ,  Don, ND6T
Would it be OK for me to use this design to produce and supply blank boards
to the ubitx community? I will do these at cost price...

Cheers.

Re: ND6T AGC and Click kit wiring notes

Nick VK4PP
 

Thanks all for sugestions....

Rich, This one is the same as Kees' in operation: RF
I was also wotking on an AF (VK3YE board) version for those who would prefer that...


73 Nick.


Re: ND6T AGC and Click kit wiring notes

Nick, it is my understanding that Kees' AGC kit works of the RF (IF)
stage, whereas your kit works off the audio stage? Thanks - Rich

Thanks Kees, I hope Don ND6T is also OK....

So far I have this. The intention is to fit it next too my HPF on the
ubitx... basically the same as yours Kees, just with components face up.
and TH also, and a pot for release time...




Re: End Fed antennas w/ uBITX #ubitx

ajparent1/KB1GMX <kb1gmx@...>
 

Chuck,

I'd ague against more than an octave for another reason, pattern. 
That and for 12, 10M and 6M up antennas get small enough there are a
a whole other set possible improvements.     I'd think if one can get a
monster wire up then several smaller antennas are possible.  A 
dipole for 6M in wire is maybe 115 inches, no excuses there.

Most do all wires tend to be among the greatest compromises.

FYI even though I have a LNR- quad (40/20/15/10) I don't use it on 15 or 10.
Its the goto for 40 and 20.   The K6STI loop on 10 is way better.  A larger
scaled version for 15 is very good.  I used a 6M scaled version in a tall oak
for FD and worked a lot stuff and had a 3 element beam to compare to.
Beam was better only when pointed that way.   Rest of the bands
(not VHF) if I want to work them I put up a monoband wire using
one favorite tree with a lanyard in it, poles, or green mil aluminum
pipe as a temporary tower.

Goes back to the first statement, pattern, you have to hear them first.

Re: Tinny sounding electric miss on uBitx

Jack Zielke
 

I know this is an old thread, but I wanted to say thank you to everyone involved.  My BFO was set to 11.995.250.  If I went 1 kHz away people were loud by tinny.  If I went on frequency, they were soft but sounded right.  I set it to 11.996.100 and everything sounds wonderful!

Re: ubitx CW straight key wiring

Gwen Patton <ardrhi@...>
 

I also "cheated", using Jim W0EB's breakout boards for the sockets and encoder. They're silkscreened with labels for tip, ring, sleeve, so I didn't wire it to "pin 2", I wired it to what is marked as "tip". So I avoided the incorrect instructions entirely.

Best purchase EVAR.

Joel,

Try changing the length of the coax on the PAR.  Something like 5FT can change that.

For cases Allied Electronics too.  They stock a lot of the Hammond products.

Re: any tips for debugging RFI issue? #ubitx-help

 

Mike,

I agree with everybody else that your getting RF back down the feed line, it happens bad on my Par EFHW on 20 meters. Thanks for unwittingly giving me a tip on where to buy my case for my uBitx, I haden't thought of Jameco. I just placed the order.

Forgot one...

Painted box, did you clear the pat at the coax connector and use the star washer?

Same for the board mounting standoffs, All of them.

Mike KK7ER,

What form of end fed 1:9 with random wire very bad without counterpoise.
Or resonant half wave (swr under 1.7:1).  FYI if not low at the desired frequency
read the manual and tune it.

FYI: a dipole without a balun or with one and a bad coax routing has RF on the coax
and off center fed is pretty bad too.

Most vertical with out a choke at the entrance are pretty bad as well. A Butternut
HF2V was the only antenna that gave me bites despite 8 radials.  The fix a 
length of LMR240 with about 50 FT50-43 toroids. before it cam into the house
and grounding the sheild.

Solutions, one is a choke balun (air or ferrite) at the shack entrance and also ground it there.
The other is load up all the wire you suggest has RF on it with ferrite.

Then again I ran into that with someone and moving the antenna (he was
literally less than 10ft under it). Didn't help that the coax used had broken off ground
in the connector too.

Insure the lead from the board to the coax connector really has the ground lead to
ground and not swapped.  You laugh...

More than like if the picture is correct... The wires hanging out of it could be as much the cause.

Power supply leads can be an path in.
