Yes I thought the cricket did not have an audible pitch with some stations. I modified the C 13 capacitor with a little Variable that helped.

Anyone else had problems with the side-tone being very high pitched? About 1200hz, I have checked the wiring, everything works and the values are correct, but the side-tone is getting close to a dog whistle 😁, thoughts?

Thanks guys, I will try and look up the mods later.

Dog whistle Cricket.
I found the sidetones mod info.
There first changed C-15 to a 30pf which did well, but later changed it to a variable (anything that tunes 15 to 60 will do). They tore one out of a cheap transistor radio, and mounted it in the battery location. They then soldered two 9v battery clips together, snapped one on the Cricket board clop and the other one onto a battery laying off the board (observe polarity when soldering wires).

Well, outside of eating Kibbles and dog biscuits, it seems like I remember a modification published on the Cricket 80 that changed the value of a cap (C-7?).
Another ham installed a variable cap over by the key and ran wires to the cap's previous location pads.
You might look for arrivals on it and compare circuitry to your Cricket 30.

My experience is that the antenna tuning can affect the sidetone for some reason.

Re: I was cruel to my cricket 40

David Wilcox
 

Shawn,

It’s a good idea to always have a fuse in every power supply line.  Then if there is a reverse protection scheme built into a rig the fuse will blow first. One time I blew an early Chinese radio (without protection) because the battery I bought at a swap had a RED price tag right next to the negative pole..... lots of smoke.  Now on all batteries I use I mask off a large area by the positive pole and paint it with red paint...... AND have fuses in ALL of my power cords.  

On another rig it did have a reverse protection diode and it blew because I didn’t have a fuse in the line.  I was lucky because I caught it right away as the diode was cooking and all I had to do was replace the diode.

Now I have confessed my sins.  I feel better!

If I were to make a guess, your audio chip is the thing most likely to have gotten zapped but I could be wrong.
