Yesterday, I blogged about working a couple of guys with Pixies. Then, I found this Tweet:

This, like most of Sverre’s posts are well worth reading.
Then, there was some discussion about the frequency of the Pixie. It comes with a 7023 kHz crystal, limiting its use in the U.S. to Extra Class licensees. WA7WNP (@wa7wnp) Tweeted, “Super cool…Now if only they had a Pixie with a crystal in the Tech band segment instead of the Extra class allocation.”
I replied, “True. You can buy a crystal for a different frequency, but that would probably cost more than five bucks!”
In response to that, John, KC9ON, tweeted:

@kb6nu @wa7nwp around 5 bucks will get you a 3 pack of 7110 7114 & 7122 (novice/tech) shipped with socket headers. kc9on.com/hc-49s-crystal…
I just ordered ten – five 7030 kHz crystals and five 7114 kHz crystals. He sells some other interesting stuff on his website, so have a look at it.
