Re: Dynamic signals on test points

Evan Hand
 

Gerard,
I do not know of a document with the TP signal pictures.  Not sure if it makes much sense unless it were under specific test conditions, as mostly you will just see noise on the majority of them.

When I disconnect the antenna, the audio is ver quite.  A very slight hiss, that goes up by just touching the antenna input.

I found the attached PDF file, maybe this will help.

Dynamic signals on test points

Gerard
 

Hello,
Is there a document with a copy of the signals seen on the scope of the test points?
I did find a documentation of Ufi Auttorri but this only gives the continuous tensions on the legs of transistors.(All is good)
I don’t understand, I’ve checked everything.
I am perfect at the frequencies on clock 0,1,2. Clock 2 follows well with the reception frequency. I calibrated everything with an average frequency of 15 MHZ. (Middle 0/30Mhz). BFO is on 11996650.
The tricoils are well cabled and the phases respected.
Everything was checked with oscilloscope and frequency meter.
I also tested the frequency curve of the 45MHZ (max at 45007680) and 12MHZ filter (Max at 11998370) . I tested the amplifier and even deactivated the CAG.It works because the beat test is very strong.
SIMPLE QUESTION: WHEN YOU DISCONNECT THE ANTENNA IS YOUR BOTTOM BEAM STRONG OR NOT? (Put the audio to the max).
Mine is weak!
The inlet filter has also been tested, and even shunted for testing.
Tests also by changing the transistors of the reception part, same finding.

I built one and now I'm waiting on replacement caps from Mouser. I'm going to use a combination of Vishay Quad High Freq RF capacitors and thru hole CDE silver mica caps.

I am pleased to see that my kit provider appears to supply genuine Micrometals T68-2 toroids. I've had poor results with Ebay toroids in the past...

Re: Current Bitx kits

Vince,
A lot of what I would suggest would be based on what you mean by experimentation.  Do you mean learning how to fix and modify hardware?  Are you interested in software or digital modes?  What test equipment do you have now, and what do you plan to purchase going forward?

For ANY rig that you go with, the most challenging area (at least for me) is the Antenna!  This will be the case for all rigs you could buy.  This is especially true if you are in an apartment, condo, or other HOA restricted living area.  You will want to save some money for this area if you have any restrictions on outside wires.  If you have a big yard with trees, then you are lucky and can skip this requirement.  Throwing up a dipole or EFHW will solve this requirement.  I did not have the room and am restricted on what I can put outside.

IF you first off want to get on the air with a reliable rig, AND have minimal test equipment and skills, then I would really look to the Xiegu G90.  It is $500, but does have all of the bells and whistles and will handle all the modes.  It also has a 20 watt output.  This is a rig that I wish was out when I first got back in.
https://www.amazon.com/Xiegu-Amateur-Transceiver-0-5-30MHz-Structure/dp/B07PQQVPDD#customerReviews

If you think that you will want to play in the hardware, then the uBITX is a good choice.  I would go with the full kit, and if after trying it with CW you find that you like that mode, then add an audio filter.  The audio filter mods do not require any test equipment beyond a DMM.  You do need a DMM regardless, even with a commercial ready to go rig.  You will also need an SWR/Power meter for antenna work.
https://www.hfsignals.com/
So with shipping, you are down to 1/2 the price of the G90, however, there are some risks and learning opportunities.  This can be a good rig, with either a compressor mic amp added or a simple amplified mic like this one that I use:
https://www.amazon.com/Amplified-Loud-Power-Microphone-Radios/dp/B0077PS0UI/ref=sr_1_14?dchild=1&keywords=radio+power+mic&qid=1600759831&s=electronics&sr=1-14
There is another less expensive one that I have not tried:
https://www.amazon.com/Cobra-M77-Highgear-Noise-Cancelling-Microphone/dp/B00006JPEW/ref=sr_1_13?dchild=1&keywords=radio+power+mic&qid=1600759831&s=electronics&sr=1-13

This will get you started, and then allow you to purchase test equipment for what was the next step planned for me which was a linear amp to get it to 100 watts.
Test equipment:
at least a 100 MHz oscilloscope
https://smile.amazon.com/Siglent-Technologies-SDS1202X-Oscilloscope-Channels/dp/B06XZML6RD/ref=sr_1_2_sspa?dchild=1&keywords=siglent+oscilloscope&qid=1600763387&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFDSTdUVTA4UVgxVFYmZW5jcnlwdGVkSWQ9QTA0NjIxOTIzTjVXM0lYUjZVRDMwJmVuY3J5cHRlZEFkSWQ9QTA1MDc2OThEQ1NKVFUwOUJINDgmd2lkZ2V0TmFtZT1zcF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl

Another receiver and or spectrum analyzer (I started with an RTL-SDR  That did not work for me, the RSP1A did).
https://www.sdrplay.com/rsp1a/

40db tap (I built this see included PDF)

step attenuator bought on eBay

I would recommend getting a TinySA and a NanoVNA. for test equipment The NanoVNA for filter and antenna work, the TinySA to verify signal purity and diagnostics of RF stages.  This is if you are going to mess with the RF power sections.

The most used test equipment for me:
1 - DMM
2 - SWR/Power meter (left in line with my rigs)
3 - Oscilloscope
4 - RSP1A (as a radio to hear transmitted signals)
5 - NanoVNA for filter and antenna testing
6 - Tone/signal generator
7 - TinySA for signal purity and RF detection

To get into the digital mode, with either rig you will need a sound card interface.  I bought a cheap USB dongle that worked well (less than $10).  That particular model is no longer available, however, there are may equivalents that will.
https://smile.amazon.com/gp/product/B08F98WSWH?pf_rd_r=23EM6GBNCCMT2TN4G1BP&pf_rd_p=edaba0ee-c2fe-4124-9f5d-b31d6b1bfbee

I also bought an EasyDigi audio interface that did solve the matching issues with the uBITX, however, a couple of 600ohm audio transformers was really all I needed.  CAT control is part of the uBITX, and I believe the G90 has an adapter.

So I have thrown a lot of information at you.  What it really boils down to is do you want to spend time and money on digging into hardware?  If so,  go low cost with the rig, and start purchasing test equipment, you will need it.  If you mainly want to operate, then put more money into the rig and focus on the modes you want to try.  Both will require antennas, so start planning that aspect, as it is the most critical to successful operating.

Feel free to bounce back with any questions.

Hope this helps, and these are my opinions based on my experiences to date.  Others may have a different point of view.

There were a few challenges:
1. The relays have 300 ohms coils. Together, all of them can consume over 12/30 = 350ma of current at all times. To save on this, you need latching relays. With them, the current can drop to less than a milliamp.
2. The relays must be of top quality as they will chatter quite a bit.
The way out is a little more elaborate:
A. Use a variable cap with a servo. Servos are cheap, capacitors are not.
B. Use high voltage FETs to short the inductors.

A small portable shortwave radio can be a useful debug aid.

The miniswr indicator above is just an LED that gets dim when the antenna SWR is suitably low.

Correct! that is what I am asking for. Purchasing the kit. IT arrives at my QTH. I assy it. It works or not. I take it out in the woods. Hook up my antenna, turn it on. Maybe it works maybe it does not Then what?

Am I getting up the creak to far or I should wait with more time to learn more about radios/transceivers?
Should I wait and learn more about it and save my money for a REAL transceiver? Is this going to waste my money if it DOES NOT work first time out in the woods?

I have an off-center fed dipole I have used portable - it does require a matching network to use.  There are other antennas to consider, find a ham to help guide you as you work on an antenna.  yes many can be home constructed.

In general, cw kits tend to be more common. QCX plus is an amazing single band cw transceiver. Qrplabs also has other kits.

In the US, qrpguys, qrpkits, 4stateqrp also have kits. Also kc9on and w8diz. Look around before deciding what you will build first.

Bitx and ubitx were offered as preassembled boards, now just ubitx is offered. Unique now to have a simple ssb rig. Many customize their ubitx with fancy displays, processing and other mods.

Amateuradiokits.in supplied enclosures for many of our earlier version ubitx. their bitx seems new.

Do look around at all the kits available. All modes can be a blast, but cw is rather special.

What I said previously was wrong:
>  The kit you pointed to is a much older single band design.

Looks like the EasyBitx is a new kit, announced on July 1 of 2020:
    https://groups.io/g/BITX20/topic/75231219#80162

Sunil has been active in this group for a long time,and many have been buying
his various offerings.  I didn't realize he had a new transceiver out.
It is single band, has an Si5351 VFO similar to the Raduino from HFSignals.
As Evan mentioned, it may provide better control of mike gain.
With a bandpass filter between exciter and final amp, the transmitter output
could prove to be cleaner than the uBitx.
The SMA cables for the antenna and local oscillator could well resolve some
issues with receiver birdies.
It might be possible to use plug in bandpass and output lowpass filters
so the rig could be easily used on more than one band.
It is simpler than the uBitx, and uses more hackable parts.
There is no mention of CW in the manual, but I suspect this could be
adapted for CW use using the same procedure as Allard used on the Bitx40.

So worth considering, especially if you are keen to have 
the full kit-building experience.

It requires much more assembly than the uBitx.

These are primarily SSB transceivers.

Subject: Re: [BITX20] Newbie, Settling on a new Bitx kit purchase. What would you recommend?
 
Vince,

Most people in this forum have a uBitx, good for all bands from 80 through 10 meters:  
    https://www.hfsignals.com/

The kit you pointed to is a much older single band design.
I'd guess well under 1% of forum members have that kit.
It requires much more assembly than the uBitx.

These are primarily SSB transceivers.
They have their warts, but are cheap and fun to hack.

If you want a CW (morse code) transceiver, I'd suggest the QCX+ from QRP Labs:

Would this be a good online store to purchase  https://amateurradiokits.in/store/easy-bitxqrp-tvrbitx20bitx40/
and what would you select/recommend just getting started with a Ubitx kit for a Newbie, such a New "General Lic Ham? I am very familiar with Kits. So not a problem ASSY this kit. But new to a "CW" kit per se. Which kit would you select for me?

In general, cw kits tend to be more common. QCX plus is an amazing single band cw transceiver. Qrplabs also has other kits.

In the US, qrpguys, qrpkits, 4stateqrp also have kits. Also kc9on and w8diz. Look around before deciding what you will build first.

Bitx and ubitx were offered as preassembled boards, now just ubitx is offered. Unique now to have a simple ssb rig. Many customize their ubitx with fancy displays, processing and other mods.

Amateuradiokits.in supplied enclosures for many of our earlier version ubitx. their bitx seems new.

Do look around at all the kits available. All modes can be a blast, but cw is rather special.
