Hi all,

I haven't had much luck making Cricket QSO's with my multiband 80m
inverted V dipole, so early this morning I decided to try the wire I use
for shortwave listening.  It's about 120' long with a lead-in wire
attached about 10' from the near end coming down to a 9:1 balun in a
plastic box mounted on the side of the garage, then coaxial cable over
to the house and into the shack.  I was surprised to find that the wire
has a near perfect VSWR on 3560 and 3580. I gave a few CQ calls and was
happy to see that I was actually being heard on the reverse beacon
network for the first time with the Cricket.

I had always been leery about trying to transmit into this antenna since
I just used 24 gauge magnet wire to build the balun and am not sure what
kind of power it will take.  But 1/2 Watt won't hurt it a bit.

The only bad thing is that I have a loud 60 Hz hum on that antenna with
the Cricket.  I don't have the hum on any other receiver, nor do I have
the hum with the Cricket on the V.  So I believe it's likely a ground
loop issue.  I'll try to work through it until I get the Buzzkill finished.

So tonight I'm going to finally (hopefully!) make my first Cricket QSO.
I plan to be on around 7 PM onward.

I found out where my hellacious buzz was coming from... the motion sensor lights on the garage, just below my antenna. So I turned them off and the problem largely went away, but I still have a little bit of a buzz on my rig. I'm calling CQ and listening out for you.

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.

Hi Jeff.

Thanks for your help. My battery is still good at 9+ volts.

 

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.

 

Just  a thought,  Jeff K9JP

We were able to QSO, him running about five watts. His signal was clear and clean. He said mine was too. He had to use his dummy load to keep the oscillator from blocking my actual signal out. 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.

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!

 

Thanks again.

I received my cricket in the mail today and finished building it about an hour ago. Nice project!

 

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!

 

Comments welcome.

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.
