MT-4 D,R,E differences
¿ªÔÆÌåÓý??????????????? I believe the VT-4R/VR-4R and VT-4D/VR-4D both require a TTL level converter for programming through either of the RJ-45 front panel connectors.? There is a member on the [email protected] that may be able to sell you a converter he makes, I do not know the cost.? The 4R and 4D use different software and one should be careful to use the appropriate software.? There is an older version software for the 4R that allows programming interstitial frequencies or a newer file that can be replaced for the newer version to program these channels.? The VHF VR-4E receivers cover the amateur band. ??????????????? The VT-4E/VR-4E have a mini USB jack on the front and can be programmed with the software currently available on the Zetron website .? The VHF 4E series program and operate in the amateur band if my memory is accurate. ??????????????? We have used all these models in the same rack, as well as some VT-3 and VR-3 modules.? It has been more of an issue to get jumpers correct.? We have also purchased a number of the DIN 46152 connectors, a DC to DC converter for 12 VDC to 9.5 VDC and they work very well.? A transmitter and receiver can be connected with very few wires and a DC to DC converter for a low current portable repeater. ? Bruce ?

? ? The receiver should program fine at 148 MHz, I do not remember the options to move the transmitter that low.
