Ahh, but just imagine if the FCC were to change the regs and limit maximum power, SSB to 500 watts.  What a uproar would it be.  I think it would be a good hoot.  Especially if all nations would limit power to 500 watts, a level playing field.

K3:VFO Noise any suggestions?

vk3od@...
 

Hi Group

I am having a issue with VFO noise on 40 meters after the K3SYN3A upgrade.

   

    1. Its not noise in my shack

    2.  I do have the VFO noise mod installed with the correct SPI settings and firmware

    3. I have had some suggestion from support.

    4. Its a very very old serial K3(below 300 serial)

    5. All mods and upgrades have been done.

    6. I did not have this issue using the old synthesizer

    7. Its only on 40 meters.


I am told and have read that its SPI bus noise. I have read  everything on SPI bus noise and  it seems that its a common EMC problem that has many  design and installation variables.


I have access to EMC equipment and can pin point the noise.  I was wondering if anyone has gone down the road of trying Kapton Tape and something like stick on foil tape to minimise radiated bus noise. I have not entirely worked out  if its conducted or radiated noise. I will be probing with a very expensive FET amplified probe soon.


I have a rural QTH with a low noise floor. I also use a beverage antenna and I can hear a pin drop.  I dont have the typical S5 to S7 city band noise! During the night the noise floor is high enough so I  cant hear the noise on the main TX antenna when tuning. During the day I can hear the noise on the main TX because the band noise is low . If I terminate the antenna ports with good loads the noise is very evident.


I have rebuilt my K3 with all the mods and upgrades. I Swapped out the TMP cables as well as cleaned all the interconnects etc. 


Any suggestions would be welcome. The K3SYNA was a worthwhile upgrade in terms of eliminating birdies/spurious products for me on the higher bands.

Re: K3 Receiver - spurious responses

vk3od@...
 

Hi  Group

I am having  a problem with spurious products  after the K3SYNA upgrade. I am  using a very early K3(less than Serial 300)   model, that has been upgraded with all mods including the VFO noise mod.

The K3SYNA was major improvement  in eliminating most of the birdies  that I encountered. I did not have the noise issue with the older synthesizer. I am considering down grading back to the older synthesizer if I cant fix this problem.

I did check for grounding and poor solder joints.  I did actually find some dry joints  by touching  the caps with a insulated tool while monitoring with a EMC probe.  I had some spare TMP cables switch I swapped as well.

I have the ability to pinpoint the noise source and I was wondering if anyone has tried   something like Kapton tape and copper foil to  try and eliminate some of these issues. I have read all that I can about SPI  buses and interference however I am not confident about cutting signal lines to place in  lumped filters and capacitors etc. I have also re-seated all the interconnects and cleaned the pins with alcohol and Deoxit etc.

I am planning on using a  active  FET probe to try and isolate the exact pins of  the noise source

I am still having issues with VFO noise on 40 meters that is very evident when spinning the VFO
I have adjusted the SP1/SPI2 settings. 

I use a beverage antenna for RX so when tuning the band the noise is a very annoying problem During the night when 40 meters is firing the  band noise is well above  the internal noise when using the main antenna for RX.  During the day on the main TX antenna the noise is obvious because of the lower noise floor. I am in a  rural area so I dont have S7 city noise that most hams have. If I use the Beverage the noise is very evident. The spurious noise is evident on  the P3 when spinning the VFO.

Its not noise from shack or switch mode power supplies. I have terminated all the ports  on the k3 with loads and I have access to EMC probes  and other EMC equipment that  clearly shows that my shack is clean.

Has anyone found  a solution to this issue? I have been in contact with support and I have had some suggestions to try and  help mitigate the problem. Any suggestions would be appreciated. 40 meters is a critical band right now because 20 meters and the other higher bands  are in a really shocking state at the moment in my area.

I’m with Tony.

 

If you’re gonna run power, go for legal limit.

 

Otherwise, stay with a hundred watts.

 

I have 153 countries confirmed on six meters. 

A HomeBrew 4CX-1000A accounted for at least ¼ of them that would NOT be in the log if I was running 500 watts or less*.

*Some F2 & multiple hop E layer openings on 50 MHz may only last a few minutes.

But to get one s unit beyond 500 watts you would have to get to 2000 watts, which is beyond legal limit. ??

Most of the time I only use 100W. Sometimes I use 500 W (KPA500). But when conditions are marginal the extra power (Acom 2000A)sure helps.

For less than one S unit would you be willing to pay near $6000 for it?

Just wondering.

Hi Dale,

With some of the nice things about Elecraft, I doubt if I would have to send the entire amp plus PS for repair. Second, I would have it remoted in my basement with my other amps so that I don’t see it, hear it or take up the space with it. It can sit alongside my other amps near the ceiling below my feet in the shack. Yep, and I agree to put sufficient funds in antennas, feedlines, and other hardware too. It is a balance for performance.

And yes, it is still a hobby, a great hobby. And it has so many aspects to it to satisfy lots of folks. Neat, isn’t it?

I have worked 345 countries on 30M with a barefoot K3. Some of those new countries were with 15W with a 56” collapsible whip clamped to a wrought iron balcony railing. Neat, huh?

1W Q’s with wire hanging out the window with a hand key are still cool.  

CU on the bands. And look for me from KP2M in 4 weeks for ARRL SSB test.

73,

N2TK, Tony

I think most hams would not care to part with $6000 for less than a S-unit better than the KPA500, not even to mention about support, and lifting the 1500 watt beast to the operating table OR shipping it when trouble happens, think about it.

Most would put their dollars into antennas and home-brew antennas at that, wire etc.

It’s still a hobby (I hope).

Just my 02 worth.

I’d be happy with 1KW. May they could then sell upgrade kits for the older KPA500.

Harry,

Unless you rag chew on RTTY and transmit several hours a day, I highly doubt you would notice any difference in your electric bill.   How much I operate a month does not seem to change my electric bill that much.  What did change it was swapping out ALL the incandescent bulbs in the house and low voltage outdoor lights to LEDs.

Not having the ability to run a 240V line to your shack, is definitely an issue with most of the high power amps. The two smaller Expert Liners will operate on 120V, but if you go "big time" with a Dishtronix Prometheus, 240V would be required.

The other option (which most consider the better), is to invest the money saved on a high power amp in high gain antennas at a descent height (if you can't hear them, you can't work them)

SURPRISE.....  Must be too costly for the K3/K3S market... For many reasons I am not surprised...

I have been in the situation where I needed more power and decided that the BEST solution was to go 12 or 24 VDC battery with solar and trickle charger backup.  With adequate planning, a >1 KW SSB DC system in not unreasonable.  I have done it a couple of times and never had a problem.  There are a few 50 VDC systems out there and amps that love them.
