Bijna hetzelfde probleem hier hahaha, scherm past niet in the housing. But is there no model, serial on the potentiometer,, , also you can take a multimeter. I think that any potentiometer with swith and the same resistor would fit.

Unfortunately, using latching relays would at least double the price of the kit. I haven't found any sources of inexpensive ones.

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.

To Jerry:

Okay. Those do answer my questions further. I am sure I will have more questions when it arrives here at my QTH and after being built. I am sure it's NOT going to work out of the box!  Hihi.
Jerry, Case closed well done, that does it. So, I will look hard into an EasyBitx or a uBitx and study the website for my needs. I own a LOT of electronic tools. So not a problem there. I even have an OWON Digital Oscilloscope and at least 2 local Extra class Hams I could ask. Also, I was wondering? If you live in the country are you a Country Ham??

(If you want to have an SSB voice rig, either the uBitx or EasyBitx could be a good choice for you.
Morse code use on these rigs is definitely an afterthought, the EasyBItx apparently does not
do morse code at all. The only other thing you really need is a friendly nearby ham you can ask questions of
and perhaps have help sort out an antenna issue or the debug the transceiver

If you are interested in CW (Morse Code), the QRP Labs QCX+ is a good choice.
If you intend to go backpacking, the new QCX-mini may be worth waiting for but 
the QCX+ will be easier to build and make modifications to.
That is a rig designed from the ground up to work well for morse code.

He can probably loan you a dummy load and SWR bridge.
If he can't, maybe get or scratch build one of these:   https://www.qrpkits.com/miniswr.html

You will need a DVM.
One of the really cheap ones from Harbor Freight is good enough, 
but a better one that can measure capacitance (maybe $10 on the web) would be useful.

You might also need to build a diode RF detector when debugging the transceiver kit.

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.
This $12 SWR meter kit is more advanced, you can actually measure forward and reflected power,
and it stays in line when you are transmitting normally.  Could use your DVM for the meter.
Perhaps use it with the 20 Watt dummy load from QRP-Labs:

To Curt:

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? BTW I can't hang ANY antennas at my QTH. I don't own a single HF antenna... All this CW stuff is so new to me I am GREEN like St Patrick's day or a Pink Puppy. Yes, my plan is to learn CW. Someday? What I am looking for is to learn something new along the way. A learning experience is my goal. Not a shelf piece to be never used and in the woods with a Dipole Ant. Yes, I like to build stuff because I learn from it. NOT books, hands-on training.

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.

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.

Re: Current Bitx kits

Evan Hand
 

Vince,
I am reluctant to give a specific recommendation as I do not know what it is you want to do, and the price point you are willing to pay.  Following are my ASSUMPTIONS about the EasyBITX, as I do not have one.  In general, I can say that the components supplied by AmatuerRadioKits have been of good quality, with no damaged goods. The instructions for the AmatuerRadioKits uBITX cases supplied for the HFSignals boards have been cryptic, to the point where I have had to rewire a couple of times until I could get it to work as I thought it should.  I did review the instructions that have been provided for the EasyBitx, and they do seem clearer.  Again, I have not built one of these kits.

- I am confused by the CW comment.  The EasyBitx does not have CW capability, as far as I can tell.  The HFSignals uBITX does, though it is a compromise with only SSB filtering width (2.7kHZ vs 400Hz). 
- The EasyBITX is a monoband SSB transceiver, the uBITX covers all us ham bands from 3 to 30 MHz as supplied.
- I have not yet seen any performance information on the EasyBITX, as far as the receiver goes.  The uBITX has very good sensitivity, with some measuring 0.1uV.  The uBITX SSB filter is made up of 8 crystals instead of the 4 in the EasyBITX.  This is supposed to provide a flatter response with steeper skirts.
- The major weakness of the uBITX has been the mic audio.  I see that the EasyBITX has gone to an op-amp to help with this shortcoming.  I do like that change.  I got around it for my uBITX builds by adding an amplified mic that solved the low power/volume issues.  That could add $25 to $30 to the cost.
- Depending on the band, the uBITX can put out 15 watts, though it does have issues on the higher bands (10 meters) where I have measured 3 to 4 watts. On 40 meters I am getting 7 to 8 watts depending on the mode and which version board I am testing (CW is lower than SSB constant tone).
- The EasyBITX is a through-hole kit you will need to solder together.  The uBITX is now an assemble kit, no soldering required if you purchase the complete kit.
- There is no track history on issues for the EasyBITX.  It is still too new.  I have not seen any reports on this reflector.  There may be a different group for it.
- The EasyBITX is about 1/2 the cost of the complete uBiTX kit.  $95 vs $209

For me, the uBITX would be a better just starting rig for a Technician class for sure, as it has CW to allow access to the Tech code bands, 10meter phone, and then can grow with the general ticket.  I think it is the better choice for a general too, though that will depend on the desired learning.  There is no soldering on the uBITX.

For a true QRP CW only kit, you cannot go wrong with a QCX+, and if you want portable operation, there is the new QCX Mini coming out.  Both do require coil winding and soldering like the EasyBITX.

Again, I cannot stress enough that these are my opinions, based on what I have experiences with assembling 3 uBITX, a QCX+, a Hermes HL2 SDR, and other kits like linear, antenna SWR meters, tone generators, and others I cannot think of right now.

Good luck with your search.

I am not quite silent key... But I have had health issues.  I had a health scare at the beginning of 2019, that led to a delay in posting updates, but things returned to normal with time out, stress reduction and exercise and dietary changes.  Unfortunately the problems then  returned in 2020.  I  had two vertebrae collapse in my lower back in March and April and was  diagnosed in March with terminal cancer (Multiple Myeloma) with some high risk factors.  I am nearing the end of Chemo treatment (and facing heavy fatigue and brain muddle at this point in the cycle).  Next month I will have a bone marrow transplant that will really knock me back for a few weeks, but all of this treatment will be worth it, if it puts me into remission for a while!  Early signs are positive.

So the site is frozen as at the beginning of January this year.  I have prioritised input into Wellington Branch 50 NZART (www.zl2wb.com) where I am chair, and into maintaining our RemoteDX project (remotedx.nz), but I have stepped down as Chair.

I think others comments about the v6  stifling development are correct. It is now a fully self-contained unit with case and graphical display and the issues have largely been addressed (except it still doesn't have an AGC and Ashhar doesn't see this as a problem), and this has opened the kit up to a wider group of amateurs who would not have previously considered the build.   The questions on the forum seem to be more in the "basic questions" category as a result.  This is less of a need for the website for the majority of buiders.

What concerns me is that ubitx.net does have some issues with accuracy and it needs to have v6 material added into the advice sections (menu items at the top). The other longer-standing issue, is that there really isn't a consolidated repository and guide for the Nextion add-on.  In fact this is a real frustration for many amateurs looking to switch out to the NExtion display.  If somebody had the time to work on either tidying up work, or consolidating Nextion downloads and guidance I am sure that the wider uBITx community would benefit immensely!

I have built and modified 2, Bitx 20's, 3, Bitx 40's, 1, Bitx 60, 1 Bitx 17, (I made a contact in Antarctica at Mirny station with this one),1 uBitx ver 3, 1 uBitx ver 4, and 1 uBitx ver 6 which I use everyday, so I guess I've had a good run but I still like to see what others are doing with their Bitx's.

Thanks Allard

Fixed my p-p v output problem. Another  self caused problem.

Now I can move on to learning about software for TX_DELAY. Wish me luck as my learning curve gets steeper. Hi

Hi again Ted,

so it seems you're getting back on track, good!

As for the RX-TX burst:
The firmware has a built-in TX-delay to prevent the spurious burst - the default delay is 65 ms but you may want to experiment with slightly higher values.
In that case you can edit line 80 and recompile and upload again:

#define TX_DELAY 65 // delay (ms) to prevent spurious burst that is emitted when switching from RX to TX
