Hi Wayne,
Does anyone at 4sqrp. use Ssb qrp? I am building a KN-Q7A 40m. Finished the receiver section which works very well when there is propagation.

Cricket people,

Here is a further Cricket mod with KC9ON's 4 crystal switch.  It works acceptable but with varied powers 1/4 to 1 watt.  The one watt is the default tall 3579 crystal.

Good morning.  Through the comments of several I made some modifications to my Cricket.  I changed C9 to 180p and C10 to 470p.  Then I paralleled R1 with another 100K making 50K and paralleled R2 with a 1K to make .6K

It works with all crystals from KC9ON but lower power.  The best was my 3550 crystal that gives me about 400 Milliwatts. Using my old 3579 I now seem to get 1 watt on my MFJ-971 tuner.  I made a solid qso with someone last night. I was excited that it worked on 3550.  It shows about the same db on reverse beacon.

I am sure interested in technical comments. Nothing seems to get hot with my regular CW and K1EL keyer.

So far it's working with 3535 3550 3560 and 3579 - all HC49/s small cases, have not seen any startup issues.  Putting the 2 pin headers in those cap positions really helped out.

>How much power does it make with the small crystal? 
Power is much lower, about slightly less than 1/2W.  Currently using an MFJ949 for measurement but really need to swap it out with my Autek meter as the MFJ accuracy is horrid in the low range.

>Does Q2 get hot?
I will leave that with a "it all depends".  If you do about 60 seconds of normal keying at 10WPM, such as calling CQ, I have not felt any heat. Probably the duty cycle is enough to keep it cool.  But if you drop your shoe on the key it starts to get hot to the touch after about 10 seconds into a dummy load. I haven't left my shoe on the key any longer than that but would assume by 30 seconds full key down magic smoke will appear.

>Does it stay in Class E?
Probably not (see above).  Someone told me of a mod to one of the bias resistors around Q2.  I have not tried this mod yet and don't know if it's better or worse.  I'm off the bench for  summer activities so it may be a while before I starting playing around again.

Another thing I have not done yet is to measure the signal sensitivity. 

Overall it's an interesting, but challenging, circuit.  I know the manual states it was a minimalist design and built for a specific purpose but us hackers will be hackers :)


For the headers/sockets........
I don't plan on re-selling them as they are very cheap (penny candy).  However, when someone asks I do drop a few samples in an order when I have extras (usually do).  I get them from TaydaElectronics.com  Their shipping costs are pretty reasonable as well.  I think they are also on Ebay as Tayda2009.   Below are the part numbers:

40 pin breakway header A-197 $.15 - One is enough for 13 crystals.
3 pin straight female header A-1069 $.04
3 pin Right Angle female header A-1028 $.09
(A header and 10 sockets comes out to around $2.07 shipped from them - hard to beat!)

The clear Mini-Yack enclosure was a gift from VE3FWF.  He does not produce them commercially but his local library is lucky enough to have a laser cutter he has occasional access to.  He has also done ones for the Chinese Pixie and Super RM Rockmite.  The software is from www.makercase.com and his current enclosures are available from several places on my web site but here is a direct link to the zip file:   http://kc9on.com/wp-content/uploads/2016/04/VE3FWF-Enclosures.zip

If anyone is interested I have a Super RM Rockmite enclosure made from hardboard I promised to give away and will send to the first U.S. person to e-mail me off list (Foreign shipping starts at a whopping $9.50 and up.... Ouch!).  You can see a picture of the hardboard version here: http://kc9on.com/ham-radio/qrp-radios/chinese-qrp-kits-2/chinese-super-rm-rockmite-aka-octopus/

Manuals for my ultrasound kits, RX1 and RX3 are now in manual form on my website catalog store.

Phil Anderson <w0xiphil@...>
 

Hey All, 

If you are interested in ultrasound reception for hunting down power line noise and/or listening to BATS and BUGs of all kinds, I"ve stopped producing the kit - ran out of PCBs - so have published a book including the manuals for the RX1, RX3 and Parabolic dish. 

If interested, go to www.midnightscience.com and click on the catalog section - far right - The full manuals for the RX!, RX3 and Parabolic dish antenna are published there in box form. 

73.........have a super Field Day........I'm running a CW station for our local club, W0UK.....

I use contest days to test my receivers. I find 40M best between 6PM and 10PM local time.
 
80M is no good here anytime. At least anytime I listen. It used to be good for local operation in the early evening and then good for DX after 10PM local time.

That's why we put the 200 foot crankup tower near the telescope. We knew we would get lightning strikes.
 
That mountain top was a scary place during a thunder storm.
 
And all the power wiring on the mountain tops was underground. We got high induced currents.

I've always heard the opposite, encourage lightning to flow elsewhere,
since lightning jumps through miles of air an excellent insulator there
is not much you can go to stop it except to make somewhere else more
attractive hence lightning rods.

I've always heard the opposite, encourage lightning to flow elsewhere,
since lightning jumps through miles of air an excellent insulator there
is not much you can go to stop it except to make somewhere else more
attractive hence lightning rods.

In the 1980's I worked at the University of Arizona in Tucson. I
worked on telescopes on Kitt Peak and Mt. Lemmon.

Lightning was a major problem. If you Google Kitt Peak (KPNO) you can
see photos of the lightning.

I received funding from the National Science Foundation and NASA to
find solutions to the lightning problem.

We found the best solution was disconnect the incoming power INCLUDING
THE GROUND at the entrance to the buildings. Then we disconnected all
the electronic systems by pulling the power plugs out of the wall. We
had jumper cables connecting all the incoming phone lines. We
disconnected them.

We also used semiconductor devices know as TRANSORBS and gas discharge
protection devices on all the power lines in the building.

At Mt Lemmon the telescope was in a low building. We installed a 200
foot crankup tower near the telescope. There is what is known as "THE
CONE OF PROTECTION". We knew we were going to get lightning hits so we
tried to control where they were.

Lightning is totally unpredictable other than the mountain tops will
get hit.

Hi Paul !

I wish I could get on the 40m net tonight, but I took a direct hit
in a lightning storm a few nights ago. It burned up my unun,
coax, and blew the coax out of its PL259 on back of the tuner. My
rig was disconnected, as always, but it also wrecked the wiring in
my test bench.

Good luck this evening.

Thanks Wayne for the time statement. I will try again at 0100 and 0130 if nothing is heard at 0030. I have been getting some SKCC contacts at 9-10 CDT but earlier has just been noise here. I will give it a go. Thanks Wayne.
