Cheap Ramsey CPO3 Code Practice Oscillator

Customer Ratings:

I purchased the kit to be used by Boy Scouts for the Signaling Merit Badge. It works very well. Not too loud to be anoying to parents. Kit assembled easily, it took me about 20 minutes to assemble, but I do have experience. With help, first time kit builders should do well.

This little thing is neat. My Kids and I built it in about 30 minutes. Would have like a little better instructions as I am not an electronics person, mostly needed more details on direction of the parts, or if that does not matter. I have had to re do the battery connector a few time mostly due to the kids letting the battery hang while they walked around with it.

This item was sent by the vendors schedule and was in a huge box, I expected a padded envelope. It took less than 1 hr to assemble, including a 1/8 in phone jack addition so I couuld use my key. It is low in volume but it is loud enough for keying practice.
