This week George KJ6VU and Jeremy KF7IJZ are together in Xenia, OH for the 2018 Hamvention. This episode celebrates the two year anniversary of the Workbench concept, and we are joined by our extended family for the occasion - Mark “Smitty Halibut” Smith KR6ZY, Kenneth Finnegan W6KWF, Gerald “Powerpole the World” Wilson KF5JNU, and Brittany Mrs. IJZ sit in for this roundtable. We discuss Hamvention impressions, spending other people’s money, and (of course) DMR this week on the Ham Radio Workbench.
Eric Swartz WA6HHQ, co-founder of Elecraft, joins us to guide our understanding of RF receiver performance specifications. Eric introduces us to common receiver specs such as Sensitivity, Noise Floor, Dynamic Range, Intermod Dynamic Range, Phase Noise, and RMDR. He tells us what they mean in real-world receiver performance terms, how they are tested, and whether it’s better to have a higher or lower number in each one. It’s also the final episode before the 2018 Hamvention and George and Jeremy share our plans for our Booth, special offers, and exclusives for show listeners who stop by booth 3104 in Xenia.
