This years virtual FDIM presentations are now available on-line for those who missed it.
Thank you for sharing this, Pete! Sadly, I was unable to attend live due to my schedule, so am very happy to see these excellent presentations. I do hope that things will be normal next year and FDIM will happen in person again. If you attend the Hamvention, I strongly encourage you to also take in FDIM–it is always an amazing event.
