I recently started working on rebuilding my radio station - this one in Evergreen Valley, a sub-division of San Jose, and small community in it's own right.

Apr 21, 2006 SSTRAN: Regarding Heat Tolerance

I had asked Phil at SSNTRAN about how it should handle heat, since I now live at the focal point of the cosmos' magnifying glass. (AKA: Tucson)

The crystal is rated to be within .002% of frequency over the temp range of -20C to 70C (-4F to 158F). The spec sheet doesn't say what happens outside this operating range. Storage temperature limits are -40C to 85C (-40F to 185F) which are the absolute safe limits before damage would occur over time.

Apr 18, 2006 SStran: Testing the built in antenna

With no ground to speak of, I got nearly 5v from the little transmitter. I'm sure once it's nice and grounded, I'll get something more substantial.

So I fine tune it (by the way - use a plastic tuning stick... boy it's hard to get a reading using a screwdriver on that trimmer..)

I hand the antenna up at the top of my blinds in the computer room. The antenna was sort of looped to the floor and then up to the top of the blinds. I was expecting to get around my house - TOPS.

Apr 16, 2006 SStran: Building the kit

So I sit down at the tiny desk I have to do projects on, and start reading the manual.

After the manual was read, I started serparating the parts by value.

About 3 hours later, the kit is built.

Wow - talk about easy. I've only ever built a couple of kits before (Ramsey FM25A, RFB 1 Watt FM Transmitter, RFB 6 Watt Amplifier) - and I screwed 2 of those up pretty bad. So I'm no expert - in fact, Stephen Dunnifer told me I should never pick up a soldering iron.

Apr 16, 2006 SStran : The kit arrives

The kit showed up after 3 days. Complete. I had the surface mount chip already installed, because I'd heard poeple say the board was crammed too tight. I did not find this to be the case. I thought the board was VERY well laid out.

I won't be using the supplied case, and I will be building my external antenna for it. But I decided to try it with the wire antenna, just to see what happens.
