last project of 2017

Terry asked what was on our benches. For once I have something to
show. After Christmas had time to button up this project. Its guts are a
Jameco power supply kit, abandoned 95% finished by a student at one of
our college club's make-and-take sessions. This is my 3rd
scratchbuilt enclosure project (2nd was a Magic Box hee hee). I'm
still learning this metal-working stuff.

Thanks Jeff. That is the kind of feedback I need. I felt sure something wasn’t right but having no previous experience with it, hard to tell. I’ll find it eventually!

 

Have a good evening.

Very Good Martin,

If you are interested in more 80 meter crystals I suggest you take a look at the KC9ON website.  See: https://kc9on.com/store/parts/hc-49s-crystals/

John, KC9ON offers 80 meter crystals on 3.550 and 3.560 MHz in the HC-49/s package.  He also sells them on ebay as well.

Another very good place for 80 meter hc-49/u or 49/s crystals is Richard, N4ESS 

 

Also, take a look at AF4K Crystals for 80 meter crystals.  See; http://www.af4k.com/crystals.htm

Bry has all sorts crystals in many different sizes or packages.  He has helped my find what I needed many times.

 

I use crystals from all three above in my Cricket and all work without issues.

 

My answer to hearing back round noise on your cricket question. I have used simple dollar store earbuds, or an 8 ohm mobile speaker.on mine.

I do hear back round static/band noise QRN and sometimes two or even three stations at once.  During the day time here, I have a local

AM station transmitter site about a mile away.  Yes, it overloads the Cricket, but as soon as they drop power for evenings I can hear stations very well.

My best heard dx would be W0ITT in MO, as well as N5JPX - MS and KD5ALD - LA.  I live in Michigan.  I would say my Cricket hears

just about equal to my FT-891 on the same antenna.  My antenna is a shortened 20, 40, and 80 meter dipole up about 35 feet at the center and the

ends are 25 feet off the ground.

Well, I hope you find a solution to your lower noise or lower audio output.   Overall, I really enjoy using my Cricket and hope you will also.

Wish, I could have been more help.

My antenna is a tuned G5RV. I’ve played with it at different times of the day and night. No, I don’t have any other suitable crystals for 80m, just the 3.579+ that came with it. I’ve got a ton of 40m ones! I’ve stayed away from 80m DIY rigs in the past for some reason. 40 seems much more versatile. I’m thinking I’m expecting too much from this thing to hear background noise which is about S3 on my 817. The fact that I could hear my neighbor very clearly and about as loud as I would expect when he was putting 5 watts into a dummy load probably indicates all is well. I’ll have to get a couple more crystals.

 

I built the DC-40a from QRPkits back in 2008 and tend to want to compare this with that one. It is amazing in sensitivity. Of course it has a lot more parts too! 😊

 

I’m not unhappy, just trying to figure out what is “normal” for the Cricket!

 

Have a good day on the other side of the lake.

Hello Martin,

I am just starting to catch up on your posts.  What are you using for an antenna?

What time of day are you listening on your Cricket?  Do you have another crystal

or crystals for use in your Cricket?  You could then change frequencies and maybe

receive a CW net (3.560)or even W1AW during a code practice transmission. 

That would give you a way to compare received signal strength between your Cricket

and your FT-817.

We are only about 200 or so yards apart. But I still feel like it is not as sensitive as I would expect. Do others of you with a Cricket hear band noise? My other two rigs hear considerable band noise even without signals present.

After reading the documentation and looking at the schematic it seems clear the issue has to be either with Q4/circuit or U1. The sidetone seems to be completely separate from that signal flow. The Q4, receive mixer must be working as a strong signal (from my nearby FT817 can be heard, even if lightly). So perhaps I messed up U1 or its circuit. I did a cursory check of voltages and surrounding components and they seem correct. I’ll keep checking.

It puts out what sounds like a clean half watt at about 3.58mhz and hears a signal transmitted on my FT-817nd.

 

But when I put it on an antenna I don’t hear any noise at all. If I transmit on my 817 into a dummy load nearby, the cricket hears that. Admittedly there are no signals on the band at that frequency but I would expect to hear some general noise – I do in the 817. I’ll keep playing. Maybe its just a bad day for 80 meters!

Good afternoon
It’s really slick here in Lebo.

It rained hard early this morning, and then flash froze about the time I was headed to work.
I went out to clear my truck and couldn’t hardly stand up!
I told the boss there had to be a better day to hit the road!
Feels pretty cozy by the fire, need to get busy with some toys!

I'm working on using one of 4SQRP's little "black" enclosures to package a stand alone keyer using an Arduino "Nano".  I ported the code over from M0PZT's original and swapped a few pins around to make the layout easier.  

I don't know if the source code is still available on the internet for this or not, but for those of you who know enough about Arduino programming and want to play with it, I'll gladly send them my version.  No instructions (I haven't figured it all out yet) and you'll have to read M0PZT's comment lines to see what everything does but it is mostly understandable and not too difficult to implement.  The diagram I have is for an Arduino UNO (the code was originally written for the UNO but the UNO and NANO have the same processor so the code is really the same for either one.

It will be a bit yet before I could send the program as I have to finish the project and make sure it will key a radio (the uBITX for instance) as I am changing the output stage from an NPN bipolar transistor to a 2N7000 (or BS-170 - just swap the position of the source & drain pins) FET.  Won't key a Bayou Jumper but I'd almost bet you could swap the 2N7000 for an IRF510 and it would handle the current of the BJ.  Worth a try for someone to play with anyway.

Hi Walter,

 

Good idea. I just checked that out. Same on both. By the way I have a good, loud sidetone in the phones when key down so I’m suspecting it is something in the RF section of the receiver. It’s possible, God forbid, that I got some of the small capacitors mixed up. I’ve got a magnifying lamp but it was very hard to read the stamped values on several of those. I tried to check them with my cap meter, but who knows. Need to study the schematic a bit to get the receive flow in my head and then start checking.

 

It is an elegant little transceiver. I’ve built a number of the 4SQRP kits offered over the years with very good success. The only one I had difficulties with previously was the power meter. I never did get it to work. I loved the NS-40, SS-40 and magic boxes! Fun to build and worked like a charm. Still have them. I added the VXO to the NS-40 but wasn’t too happy with the result. Need to lash them together again and blow out the dust!

There are software fixes for that too, but I'm waiting until they go to a different keyer.

The EZ Keyer series will work great and my little FET keying interface should not be needed with it.

GM JIm,

"The internal keyer is being worked on"

Which keyer are you using?   The smd EZKeyer II-i is ideal and was designed for this application.  http://www.4sqrp.com/ek2i.php

GM Yvon,
Attached is the schematic of the keying adapter I used.  The 2nd and third stages (for the key paddles) did not help enough due to the poor implementation of the paddle keyer.  I suggest using only the first stage of the adapter in the schematic, (disregard everything to the left of C4 on the diagram.).  For 90 percent of the people that have used it, this improved the keying for hand keys and even allowed using a bug.  Use an external keyer either through the adapter or if the external keyer has an FET output keying stage, the adapter should not be needed.  The internal keyer is being worked on but it's going to be a lengthy process and for now the suggestion is to use an external device.

Jim,

do you mind sharing your modifications for CW? I have one too and in CW it is not ideal but it is a quite receiver.

Thanks,   73.

OOPSIE - you are absolutely right.  Use only the first stage.  I hadn't had any coffee yet when I posted that so my old military training (your other left, dummy) kicked in - LOL.

Disregard everything to the RIGHT of C4.

I think you meant to disregard everything to the RIGHT of C4 in the diagram, didn't  you?

Everyone: Don't forget the SSS is this Sunday, from 7:00-9:00 CST (0100-0300Z).  Full details in the rules, available on the 4SQRP website.
