This page was put together to help answer questions about the Autoshift.
The Autoshift does not seem to respond
If the Autoshift unit seems to be completely 'dead', here are some things to check.

  1. Check for 5Vdc on at the 706 CI-V connection point. There have been reports of bad solder connections in the 706 that affect this. The CI-V should indicate 5VDC on it even with the Autoshift kit installed.

  2. Check the connections in the 706 that you have not made a solder bridge between the CI-V connection point an any of the nearby traces. The 706 traces are covered with a solder mask (Green color) and a hot solder iron can expose the copper trace and cause a short.

  3. This is a solder short in the 706. This has been the only problem when the Autoshift appeared "dead"

After installed the Autoshift, the radio has no output power on HF

  1. There is a known problem with the 706s where the HF TX power drops.
    The main two problems are a bad filter relay and shorted diode/transistor in the filter unit.

  2. Also, check the CI-V connection in the 706 for a solder bridge. Even tho the traces next to the CI-V connection are covered with a solder mask (The green colored coating), there still can been a very small exposed trace. If a solder "short" is made between the CI-V connection and a trace, this could cause improper operation of the radio.

Autoshift "shifting" when I key radio.
The Autoshift is enabled when It sees the Narrow filter being turned on. However, if you power up the radio with the narrow filter ON, the Autoshift will NOT see the radio as being in narrow mode until you turn OFF narrow then back on. On the MK-II, the narrow filter in FM mode can be enabled in each VFO-A and VFO-B independently. The 706 "classic" will enable them together. That is, you can have the narrow filter enabled on the B VFO while it's off on the A VFO. What happens is if you have the narrow enabled in the B VFO, when you transmit in split mode, the radio will switch to the B VFO (as normal) but since the B VFO has the narrow filter on, the Autoshift will see this and "spring in to action". When you keyed the mic. the radio effectively enabled the narrow (when it switched to VFO B) and also it saw a change in frequency (even in simplex). This is all the Autoshift needed to think it had been enabled. The key is to make sure that the B VFO does NOT have the narrow filter enabled (Note: This is for the MK-II only)
