| 3 | This error means chirp got *no* response from the radio at all. In almost all cases, this means a connectivity problem (although it can occur if you select the completely wrong driver for what is connected). The **most common** reason for this problem with inexpensive radios and connectors is *a fitment issue**. Other reasons include bad cable connections, faulty drivers, etc. |

| 7 | # Workaround |
||
| 8 | |||
| 9 | If you have an inexpensive radio that uses the Kenwood K1 connector (the ubiquitous dual-pronged 90-degree one), you can probably work around the issue by pushing **very** hard to fully seat the connector, or even by trimming some of the plastic around the radio and/or the connector itself. |

| 11 | # Solution |
||
| 12 | |||
| 13 | The best and most obvious real solution is to obtain higher quality hardware made to more exacting standards. The CHIRP project recommends high-quality FTDI-based cables from BlueMax49ers, which generally also have high-quality connectors that minimize problems. Note that just because you're using the cable that came with your radio or the one your radio manufacturer sells/recommends, does not mean it is the best one available. |
