I have placed order for PCB two days ago. The first batch is 350 pcs.
I have finalized the parts value and will place order for parts tomorrow. The RF output is 1-watt at 12V for 14.074MHz, and a bit bigger for 7.074MHz. The spurious suppression is better than -50dBc.
I hope to start kitting for the first 5 pcs on May 4. If it goes smoothly, I might take order to ship these kits early, so you can send a few test reports ahead of time than the usual customers. Stay tuned and I hope you will like it.
