Digital vs Analog/Dial
Digital vs Analog/Dial
I`m a beginer when it comes to shortwave radio listening.
I once had a Realistic DX-150. This radio has the dial to turn to tune the stations in.
I enjoyed tuning stations in with this reciever.
But I noticed station drift quite abit on the stations further away.
Do the recievers with the digital displays get station drift? Or is this something in the reciever that needs calibrated?

It could be either. Depending on just how far away, and how strong a signal they are producing, propagation can really do some 'tricks' with frequency. Especially on some of the older receivers which may not have been as 'regulated' or accurate or stable as possible. The newer digital receivers tend to be more stable, but they have limits too.
With the older radios that the dial turned a variable capacitor, lots of things could affect how much that capacitor had to be 'tweaked' over time. The newer digital radios are almost all tuned in 'steps' of some size frequency 'jumps'. There's no 'variable' thingy that requires 'tweaking', it's all in the 'inputs' to a chip.

"Thingys", "doo-dads", etc, are all technical terms that deal with a large number of variables of almost every sort. If the discriminating reader pays attention to their use, that reader will understand that there are many situations where more information might mean a more specific term use. That discriminating reader should also keep in mind that their usage may only signify that the user of those terms is just too @#$ lazy to say it correctly, too much typing.
