Re: 5w on 40 meters

Dave Dixon
 

Here are my results on my V5.
80...14 watts.
40..  10 watts.
30    9 watts.
20    10 watts.
17 to 10 mtrs 5 watts.
the only mod is fit the cw keying resistors and a 5 inch TFT screen.
worked indonisia on 9th october 2019 with 579 on 40 mtrs;
verified via eqsl.

I also have a V3 with 2 line blue lcd this delivers
17 watts on 80.
14 watts on 40
11 watts on 30.
12 watts on 20
 9 watts on 17.
 7 watts on 15.
 5 watts on 10..
again no mods only the cw resistors.
Im very impressed with both radios.

all my radios are home made from kits..
i dont own any commercial radios at all save for a 2 mtr fm transceiver
thats the only microphone in the shack..
Aerial is an off centre fed dipole at 25 feet.

I have found the BitX40 to be a nice SSB rig and I am curious about your feedback problem. Are you hearing yourself through the speaker when transmitting? What microphone are you using?

Tom:

Perhaps things are different there than here, but we have a very close working relationship with police, fire, and other emergency agencies. We work with hospitals to provide coms between medical support stations for everything from local marathon races to parades and other public events. This frees both EMT and police manpower to be deployed more effectively. While we have independence in our assets, we work in concert with local agencies when asked to do so. We even had local police and fire chiefs attend our local meetings so we can inform them of our capabilities. They genuinely appreciate such efforts.

Your view that our job is to handle messages for citizens is far too narrow. Our ARES services do very little of that. We augment public emergency services, not replace it. We see our abilities as an adjunct to their facilities and can help direct those resources where they may be needed most. During an emergency, they may be stretched so thin that they can't deploy enough manpower to know the real danger spots. We can help with that.

My guess is that some percentage of µBITX users also have a 2M HT or bases that can touch a repeater. It would be a shame for expensive applications, fees, and rents to lessen that ability should an emergency arise.

I suppose this has some relevance here, as some people here are getting groups of hams set up with uBitx radios to form emergency communication networks. 

So lets look at this from the myopic perspective of the government agencies. Their view of the world is so the police cars driving around and the fire trucks going to calls can communicate. They have no interest in handling messages for the citizens. Or providing a communications lifeline for citizens when all other forms of communications for the general public have gone down. 

That is the importance of Ham radio, to provide the communications lifeline to the citizens during emergencies. Because the Amateur Radio operators have taken it upon themselves to develop an independent communications network and give of their time to maintain the equipment, train and organize the people to provide this communication service to the people that the official agencies will not provide.  

So, it may be best to just forget about the idea that we have any use to the official agencies and all their fancy communication networks as they drive around in their vehicles. (Admittedly a very important thing.) And concentrate on Amateur Radio as being the communication lifeline for the population at large, who will be left behind as far as communication needs, when disaster strikes.

Re: 5w on 40 meters

My v5 is following the same pattern of output power vs band and I’m not terribly worried about it.  As Curt said the difference between 5 and 10 watts results in only a fraction of an S-point on receive.

funny thing, my own v4 has a similar response of low power on 40m CW.  interesting you are getting it on a v5.  I am getting around 5w or so using a WM2 wattmeter on 40m, maybe just around 10w or so on 80m, and a boost in power as you see on 30 and 20 meters. 

I think the v5 retains the toroids feeding the 45 MHz xtal filter as in the v4?  now what might these have to do with CW transmit?  well I suspect some strange leakage involving these coils and other parts, as the ubitx seeks to 'leak' CW from the PLL direct through the mixer - without mixing as the diodes are biased.  as I tried to install a second xtal filter, the 40m leakage matter had more impact and my 40m output dipped a couple watts only.  

I am thinking you should enjoy what your nice rig does.  If you have an audio oscillator, you might find that you have better SSB output on 40m?  I don't see it is worth a lot of work to get from say 5 to 10 watts CW on 40m - its a tiny fraction of an S-unit. 

some have replaced those 45 MHz toroids with little (but high enough Q) shielded inductors, curing some spurs that mar the v4 on SSB and as part of the harmonic cure.  I have some, but not yet installed (I am enjoying a clean signal on lower bands already).

I tend to see a nice enough v5 you have.  it would be good to hear if any other v5's are doing this - but I don't see a huge reason to fix what you have.

Thanks.  I've got a working radio and don't want to mod it (I have no use for CW and want it pretty much stock) - I was hoping to learn of a setting in WSJT-X to make it work with LSB.

(I'm sick of having to work on stuff - long story - and would just like to be able to operate - and actually make some contacts.)

Is there some way to get WSJT-X to function with lower sideband?

Also, a minor problem - the radio board is microphonic when the audio is turned up.  I've gone crazy trying to find the source - it's somewhere in the middle of the board - but I can't find where (no matter how much I tapped with a non-conductive object.  Trying to use the radio for SSB - the feedback is very irritating - like an echo circuit.  (It would be nice to be able to use the radio as intended - if I can get through/past the Kilowatt crowd.)

Any suggestions on what component might be the problem?  (At lower volume levels, you just about cannot tell that it's there.)

5w on 40 meters

Maurice Bersan
 

So I decided to check the output of my stock v5. These are the results CW.
80m  18w
40m    5w
30m    14w
20m     10w
15m     7w
10m      4w
Used two different power meters and two different dipole antennas and two different tuners. I don't have a lot of test gear so any clues as to where I should start looking?
Thanks in advance

Also, a minor problem - the radio board is microphonic when the audio is turned up.  I've gone crazy trying to find the source - it's somewhere in the middle of the board - but I can't find where (no matter how much I tapped with a non-conductive object.  Trying to use the radio for SSB - the feedback is very irritating - like an echo circuit.  (It would be nice to be able to use the radio as intended - if I can get through/past the Kilowatt crowd.)

Any suggestions on what component might be the problem?  (At lower volume levels, you just about cannot tell that it's there.)

Thanks!

Don

glad it was operator error - it happens.  appreciate all your posts here.

I have a U3S for WSPR - its 200-300 mW reach VK, ZL, ZS and Antarctica on 30-40m.  I need to build a few watt PA for 80 and 160m for it.  I keep also thinking I should put my ubitx to work to do some WSPR receiving for others.

PS do study the daisy-chain arrangement of relays in case you do have an issue. note a lot can be tested with an ohm-meter as relays get toggled by band switching.

All good, you are correct – IO has the ability to ignore threads so that’s all fine.

Pretty much history here. You guys have a far better relationship and understanding with fire and law enforcement which would be the envy of other countries including New Zealand, so it is worth fighting to retain it.

Probably doesn't, so read the subject line, then delete it...although I suppose you could face similar problems over there, too.

How does this relate to BITx and those of us outside the USA?

I disagree Arv. I started a new thread specifically so I wouldn't tread on an existing post and members could judge their interest in the topic. Personally, I think every ham should care about the topic, but some won't, perhaps because they see it as a State problem and, hence, not affecting them. As I recall, HOA antenna restrictions started out the same way, and soon spread throughout the US. Anyway, I think my subject line clearly stated the thread's content and is more informative than a generic "info-topic" subject line would be. I think the additional details makes it easier for someone to simply erase the post if they're not interested.

Occasionally there are actions that have great potential to affect ham radio as a whole

but start as small local changes.  Maybe the topic for posts about these events should

be labeled "info-topic" so that those with very narrow fields of interest can avoid reading

them. 

 

We do have quite a few "off-topic" posts from time to time.  Maybe the solution would

be for moderators to allow the particular topic to run for a few days and then lock the

topic so that no more re-posts on that topic would be allowed.  This seems reasonable

but does potentially block later readers from commenting (good?, bad?).

It's specific to one state of one country, and there are literally dozens of more suitable venues than this for any discussion of this subject.

 

How does the policy of CalFire in California, USA Regarding repeater space on public land n the state of California impact the Lithuanian trying to assemble an HF station based on a uBitx or Bitx40?

I suppose this has some relevance here, as some people here are getting groups of hams set up with uBitx radios to form emergency communication networks. 

So lets look at this from the myopic perspective of the government agencies. Their view of the world is so the police cars driving around and the fire trucks going to calls can communicate. They have no interest in handling messages for the citizens. Or providing a communications lifeline for citizens when all other forms of communications for the general public have gone down. 

That is the importance of Ham radio, to provide the communications lifeline to the citizens during emergencies. Because the Amateur Radio operators have taken it upon themselves to develop an independent communications network and give of their time to maintain the equipment, train and organize the people to provide this communication service to the people that the official agencies will not provide.  

So, it may be best to just forget about the idea that we have any use to the official agencies and all their fancy communication networks as they drive around in their vehicles. (Admittedly a very important thing.) And concentrate on Amateur Radio as being the communication lifeline for the population at large, who will be left behind as far as communication needs, when disaster strikes.
