what does the RASP in the yaesu radio line mean?
@Tom_Lewis the letter R is a common ending to radio models. Re: ASP
FTM-150RASP - The Super-DX function increases the receiver sensitivity and improves weak signal reception. The new ASP: Audio Digital Signal Processing Unit is also activated when the Super-DX key is pressed. The Super-DX with the ASP ensures reliable audio quality for weak signals and expands the communication range. Additionally, expand your operating capabilities with both FM and C4FM (SystemFusion) support on the FTM-150RASP.
FTM-310RASP - The FTM-310DRASP features the Acoustic Enhanced Speaker System (AESS) which generates a total of 6W of clear, high-fidelity audio from its front and main-unit speakers. A key advantage of this model is the integrated Super-DX + ASP (Audio Digital Signal Processor) function. When operating in FM analog mode, the ASP can be activated in addition to Super-DX, with selectable AUTO and MANUAL modes. It’s important to note that when ASP is active, the main-unit speaker will not sound, but the 3W front speaker inside the control head ensures clear and powerful audio.
