    Of the approximately 40,000 men who served on U-boats in WWII, it is estimated that around 28,000 to 30,000 lost their lives.

                    72MHz synthesized module still could be find, and synthesized receiver can be get them from china.

                    If you're ground range test in your "bathtub"...

                    Add a Frequency checker in your tool box.

                        From what I've heard 72 mhz has a range of around 2-3 miles (5 if conditions are right). So, how sure are you that on the day you're out on the pond driving your sub someone with a plane with old school tech ( 72mhz) a couple of miles away is setting up? If you could mess up his flight he can mess up your dive. At the end of the day someone's going home with just a transmitter.
                        Even if that did happen the models would mostly respond to the transmitter that is closest to them. Your submarine would likely start having some glitches but still do what you commanded overall.

                        My favorite radios to use are Futaba PCM's. They can go for a fair bit on ebay but you can find them at model airplane swap meets for next to nothing and sometimes free. These are usually computer radios that where very expensive when new in the 1990's to early 2000's. You can find them in 75mhz but much more common in 72mhz (in USA) You do need a PCM specific receiver. Futaba ones are quite common. The transmitters are usually capable of switching between PCM and PWM.
