Picture of the current circuit might help... I don’t think we will be able to pull it off but it could be a fun thought experiment... transmitter is unlikely... you’d need something a bit higher end to do that (as I recall Maxitronix 200-in-One Electronic Project Lab https://www.amazon.com/dp/B0002AHR04/ref=cm_sw_r_cp_api_bNAtAbZH2F7BV had a basic transmitter)
