Re: Odd Raduino, How do I Connect it?
#bitx40
I have same raduino, when looking at the back what orientation should the cables be? AKA what colors to what pins.. Anyone have a pic of their raduino?plugs so I can see.. I blew my voltage reg on my raduino plugging it in wrong, making sure I dont make same mistake 2x?

So if I buy LPFs from Hans, which bands would you recommend? Given that the even harmonics are fairly well attenuated, I'm assuming I could use 1 LPF for 2 bands (ie 40/ 30, 20/17)?? Given the current solar flux disaster,? I probably have several years to solve 15, 12 and 10. Alternately, the BPFs for each band.? I'm not ready to give up yet!

Re: Can we start using SUBGROUPS? uBiTX, biTX40, QRPKITS, Original BiTX20, Homebrew, Other?
Seriously? Lets advocate for splitting the group up but if you can't get help its the hunger games.
No division is required, just the ability to use a search engine.?

Re: Can we start using SUBGROUPS? uBiTX, biTX40, QRPKITS, Original BiTX20, Homebrew, Other?
Indeed !
Thats a QRP Labs stamp collecting in a QRP Labs specific group!
Who is going to be first to get the other two denominations of
stamp?
Oops, wrong group.......

Re: Can we start using SUBGROUPS? uBiTX, biTX40, QRPKITS, Original BiTX20, Homebrew, Other?
I have also stopped reading most posts, and not replying.
Seems like most posts are made by the same few people.?
Some of them are thoughtful and put ubitx in the title/post, a couple of of them think they are too special to do anything like that.
This group to me is a total mess. I have a?¦Ìbitx. I am not interested in the 40? or the 20!!!!
The fact that many people would have to be moved over or rejoin a meaningfully named group just illustrates the extreme short shortightedness? in the first place.
Of course the chances are that no one is interested in what I do or what I have found with the four?¦Ìbitx I have, we'll never know as it is at the moment.

So will I see these subgroup posts via firefox or do I have to logon to BIT20 group.? Looks like I will miss
a lot of posts.

No need / better without mods moving topics to correct groups.
If you don't get a reply, the question was not that important to that group.
It's the same as posting a ubitx specific question to a stamp collecting group, do you expect a reply?

No mod's need to do anything...
It would actually make it better that way in the long run?
It should be self policing?
If you post an "how can i increase my output power question" in a
software sub-thread.....
You may get a reply stating you are in the wrong place.
either way if you don't get any reply, you think to yourself why
not?
and you might realise??

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
Gordon,
Good to see you are making positive progress.
Re:- the before & after figures
I don't know the Icom 718, as a background just in case someone else
tries to repeat your tests. It's normally quoted as 6dB per S point.
Pretty much all radios will be different. Its a repeatable test to
the same reference value on the meter on the same radio but not
necessary beyond that, the meter reading may be non-linear etc.
Alison suggested the stepped attenuator approach to bring the
fundamental down to the same indicated level on the meter as the
harmonic, the amount of added additional attenuation indicates the
harmonic reduction.
The measurement accuracy is then transferred to that of the
attenuator,? and is more easily characterised.
It is also transferable to other peoples measurements regardless of
method, by radio or a spectrum analyser etc.
Can Alison comment?

Able to charge that battery significantly and proceed with tests.
All of these have a homebrew 50 dB tap on a Heathkit Cantenna, and
then a 20dB attenuator at the input of the ICOM 718.? ?Previous
measurements have suggested that between S7 and S9,? ?an S unit is
approximately 12 DB.
Presented witll be the BEFORE/AFTER? ?S unit measurements where
before is the relatively STOCK uBitx and the AFTER is is with my
external daughterboard, with basically unshielded wiring.
All measurements are for CW (because this is where the unit had
the most problems)
Power is estimated from a Micronta cheap SWR/power bridge built
for CB'ers many many years ago.??
FREQ? ? ? PWR? ? ? ?FUNDAMENTAL? ? ? ?2ndHArmonic? ? 3rdHarmonic?
?4thHarmonic? ? 5thHarmonic? ? ?6thHarmonic? ? ?7thHarmonic

/? S6? ? ? ? S0 /? ?S0? ? ? ? ? ?S8 /? S1? ? ? ? ? ? S0 / S0? ? ?
? ? ? ? S8.5 / S8? ??
(so on 80 meters, the 3rd and 5th harmonics were greatly
attenuated, and the 7th lost maybe 6 db)
7.005? ?2.5/3.5W? ?S9+30/S9+30? ? ? ? ? ?S0/ S0? ? ? ? ? ? ? ?S8.5
/ S7? ? ? ? ?S5.5*/S0? ? ? ?*=wavering
(so on 40 meters, harmonics went? down by huge amounts
9.995? ?1.5/1.5 W? S9+30 /S9+30? ? ? ? ? S0 /S0? ? ? ? ? ? ? ?S9 /
S5 or less
(so on 30 meters, the 3rd harmonic was basically demolished)??
In previous testing on 14 MHz, I cant go any farther than the 2nd
harmonic and it was S0 (no reading) so not much for me to work on
profitably there...and that is the filter that I damaged.
This looks overall, like a huge success.? ?The only oddity is the
7th harmonic of the 80 meter signal (why??)? ?but even it may be
down 42 db.? ?On these bands, my crude testing indicates that even
CW now either passes with flying colors or is very very close to
it.? ?If I shield or even twist a ground around the INPUT (red in
the photographs) wire it may get better.

Sorry; can't edit...

No more than 3 or so?

Re: Can we start using SUBGROUPS? uBiTX, biTX40, QRPKITS, Original BiTX20, Homebrew, Other?
I vote YES.
It's difficult to suss thru different threads - so much so, I've stopped reading it (to a large degree).
I have a 'first gen' (Ver 3 PCB?) - and an older BitX20.?
It's just hard to wade thru; and I can't really contribute to some.

Although not indicated on the schematic, I also removed

I also started to work on the filter modifications. I

Re: Right-sided relay harmonic attempted fix for v3/4 ubitx
?Great!? ?Perhaps it will help some people who are concerned about the harmonics.? ?The total cost of the kit boiled down to
$2.50 or less for the board when purchased in quantity of 10 or so from China even with 1 week DHL shipping
$11 or so for the three relays
$2 or so for the inductors and capacitors
Use IN4001-1N4007 for the diodes (I should have speified that!)??
So about $15 and some elbow grease to really knock down the harmonics.? ?I pay more than that for a 12V battery!
What a great ubitx transceiver Ashar F. developed for the world!
