     leobodnar.com was listed in a QST article in August 2022 as a source for a GPS time base for use with an ICOM IC-7300 HF transceiver.  Might work for you.

   I use the QRP-Labs Gps board and Oscillator and the RF-Zero board.   
   Both use recent generation of GPS chips.

   Anyone have any experience with using a GPS disciplined oscillator as an external reference for their radios? Think my 1310 exciter and 2368 receiver both can use a 5 MHz external reference and was thinking that I was going to buy one of the Chinees GPS disciplined oscillators over on eBay primarily for using as an external 10 MHz reference for my service monitor and a couple other items on the bench but was also thinking of throwing together a distribution amplifier and maybe a divide by two output for the Harris stuff, don’t remember but think maybe I can use an external reference with the RF-350 also?  Would be curious to see if others have any experience with the China boxes and reliability and what happens in a high RF environment?
