Re: Newbie Issues

Ed Gable
 

Hello Jim:  Thank you for your prompt and helpful response to my plea for assistance to my BJBlue issues.  I regret I've been tied down with family needs but am now back and the Jumper is working great.  I'll be brief (yeh, good luck with that :>)   My RX issue was all with Q2.  First MPF-102 was DOA.  Second 40 year old junk box 102 oscillated was also problematic.  Read on the 4State news group of J310's working well and found a U310 in the junk box which was the whole problem.  It worked right away, 7 Mhz looked OK on TP1, but really unstable, noisy and rough sounding signals and no hiss but more of a buzzing sound.  I have an older but nice HP spectrum analyzer with a rarely used FET Hi-Z test probe.  With that on TP1, poof,  there it was a nice 300 MHz spurious band of junk.  I got a J310 from a friend instead of that UHF rated U310 I had been using and everything instantly fell in place with 22 pf installed and the 4 turn link now readjusted from super tight to "normal."   You asked about the LED current.  I actually had not wired the LED's yet but now running about 24 Ma in RX with some peaks when pushing audio harder.  Yes, I'm hissing when I want to and hearing background noise with no signal is the norm.  Frequency range is good and I'm tweaking for linearity over the range but probably as good as it can or needs to be.  So the end result is good, it's been a fun project with just some bad luck in the beginning.  Thanks for all that you do for the group.  Warm regards, 73  Ed Gable  k2mp

Hi Ed,

Since a regen is most sensitive and selective right at the onset of oscillations your detector is doing its job and its level is good.

Are your red/green LEDs working correctly? They consume 10 mA or so of that 20+

It may be tough to get a good MDS measurement because the Rx input impedance is more than likely not a good match to the sig gen.
The real test of sensitivity is can you her all the way down to the ambient band noise.

Do I understand you correctly that you hear no background hiss or noise but still hear signals?
What are the voltages measured at the pins of U1?

U-310 ought to be fine as a sub for J-310.
If I'm not mistaken the U-310 is good well into the UHF range, since its noise figure has a 450 MHz specification. Its current and threshold voltage specs are in a good range.

Jim, N5IB






Re: Planar Transformer

That is really cool. So Bourns is making them. I wonder how they would work in a final - have to be QRP...

Planar Transformer

Tim N9PUZ
 

I was reading an announcement about a new POE Hat for the Raspberry Pi computer board. What caught my eye was mention of it using a "planar transformer" in the circuitry instead of a wire wrapped ferrite core. The planar transformer has the windings etched onto a small PC board which is then sandwiched between two pieces of ferrite to form the transformer. I have not seen this technique before.

Here is a link to the article. A picture of the transformer appears at the end.

GA everyone!

Just wanted to put out a quick note regarding Moderator response time. We currently have a couple of people who are unavailable to help out, so our response to owner/moderator questions may be a bit delayed. We still expect to turn around a request within a day but in most cases we like it when we are able to respond in a more timely fashion.

Thanks for listing the original features, I need go get mine out to find the dummy load (-:

See my list from earlier posting, I still think its got the most usefulness to fill in gaps that builders may lack - lc measurements, precise signal generation with 2 levels etc. Okay to keep its control spartan and less essential to provide a case, okay that may be controversial. Idea is to provide a useful tool set to the builder, I see n5ib made a major contribution.  

Let's see where it goes, but I sense a lower cost instrument will sell more than an exotic.
