The FT-70D is a 2-meter FM mobile transceiver from the mid-1980s that remains popular among ham operators who appreciate simple, reliable equipment. It delivers roughly 50 watts of RF output on the 2-meter band with a straightforward interface that doesn't require a manual for basic operation. Most users find it easier to pick up than many modern radios precisely because there are fewer menus to navigate.
The radio features dual VFOs, 80 memory channels, and an analog S-meter that gives you a reasonable estimate of signal strength without being overly precise. It accepts both 12V DC power and has a built-in speaker that produces adequate audio for mobile use. The frequency coverage spans from approximately 144 MHz to 148 MHz for receive, with transmit capability across the same range.

Frequency stepping: 5 kHz, 10 kHz, 15 kHz, or 5 kHz depending on your regional allocation. Memory channels: 1-80 with alphanumeric labels possible through the programming cable. SQL (Squelch Control): adjustable from 0-10, with lower numbers opening the squelch wider. AGC: set to NORMAL for most situations, though FAST can help with weak signals in noisy environments.
The dual VFO system works independently, meaning you can store one frequency in VFO-A and a different frequency in VFO-B, then swap between them using the dedicated button. This is particularly useful when operating from a fixed location where you monitor a simplex frequency on one VFO while keeping a repeater input on the other. The split function allows simultaneous receive on both VFOs, which some operators find valuable for monitoring two frequencies at once.
Memory programming requires either the programming cable (part number YSO-10 or similar) or direct keypad entry through the menu system. The 10-step frequency entry mode lets you input frequencies digit by digit, which takes practice but becomes faster over time. Many operators prefer the cable method for bulk programming since entering each memory channel individually is tedious and error-prone.
I found that the analog S-meter takes some getting used to. Unlike digital readings that give you an approximate Signal-to-Noise ratio, the analog needle movement is somewhat subjective. You learn to associate needle position at about 3 o'clock with a reasonable 20 dB signal, while a position near 12 o'clock indicates strong signals above 40 dB. This estimation improves with experience but won't replace actual RST reports from operators on the other end.
The backup battery compartment contains a 9VPP3 battery that maintains memory settings when the main power is disconnected. Without this battery, or with a depleted one, all memory contents and settings are lost upon power loss. I replaced my original battery every few years with a modern equivalent, as the original cells tend to leak after several years of non-use.
Common issues include the main fuse blowing when power is connected backwards, the frequency display becoming dim or illegible as the fluorescent lamp ages, and the front panel connectors becoming loose with frequent cable insertion. The synthesizer circuit is generally reliable but can develop frequency drift if the internal components age, particularly the VCO section.
For operators interested in this radio, the FT-70D represents solid mid-range performance from an era when Japanese manufacturers prioritized reliability over feature count. The absence of advanced digital features means fewer things can go wrong electronically, though you sacrifice the convenience of CTCSS encoding and other modern conveniences built into later models.
