In June 2020, I ordered 2 ea crystals set's for the LSB and USB BFO to get 2ea Collins (75S-3B & C) back on air. Mid July the new crystals where fitted to the radio. Turns out that the radio is fine in LSB, however USB is not working. X-checked for the correct installation of LSB and USB crystal’s, all correct. The crystal BFO was running on 345.650kc (LSB), regardless of the LSB/USB mode selector. My measurement showed that all 4 crystal's are on the LSB frequency.
All these details where passed on to Inrad and asking for an explanation. A first response received from OM Scott W4PA, where he is requesting the markings on the crystals. The requested details where passed on to Inrad / OM Scott. The response was that Inrad will check the inventory of these crystals and measure the frequency response. A reminder was answered on Aug.22 2020 with: “which crystals are missing and we will mail them to you” …
A new status was requested. On Sept 15. 2020 OM Scott answers that all (USB)crystals in stock are wrong. Inrad is waiting for replacement for the manufacturer. They are due any time.
This was the last response from Inrad. Further mails including a mail on April 15. 2021 asking for a reimbursement of the 2 ea erratic crystals remain unanswered. No further response fom Inrad received as of today, may 26. 2021. I am fully aware that Inrad did not manufacture the crystals in question, however as a customer I feel been left out in the cold.
This is not the behavior of a reputable company.
