>> A local NTMS member alerted us to an ebay listing where SP2JYR is selling the XP version of the Wavelab board. This morning there are 8 units available. The listing appears under "bisonelectronics-sp2jyr" but I had to search on "23x1008xp" to locate the listing.

>> Processing a tentative order of PA0HME pcb boards this morning reveals that JLCPCB has about the same parts shortages as back in November 2022 when I ordered 20 manufactured boards. They do now have the mixer in stock and the ATTINY which means you would need to program the ATTINY in circuit or I can do that at no charge. The manufactured boards would run about $70 each which includes shipping domestic from here in North Texas. In the last run we helped some builders acquire the extra parts from our own stocks but they are all available from Mouser except 1 or 2 that are found at Digikey.

>> We have built 4 boards within North Texas Microwave Society and Mike Lavelle, K6ML has built at least one board in California. We are measuring RF output in the 30-33 dBm range at 24192.
>> 
>> All 20 boards from the last run are gone. If you are interested in acquiring a board in the next run, please let me know.
>> 
>> The parts "shortage" list is attached but keep in mind you do not need all of these parts depending on whether you will utilize a bias-T and depending on your pad requirements from your IF transmit level. We have a project parts list at Mouser that can help the ordering process.
