Tower complained of weak/broken for my SV radio until I switched from Halo to Bose A20. All good now. The Halo picked up too much engine noise (straight pipes).

Already using an A20 and can't transmit on 122.7 with the engine off.

Default Same Issues

I have had very similar experiences as many on this thread and the OP. I have the Skyview Classic suite, Delta Pop comm antenna, Zulu 2 headsets and built a 2016 Rans S-20 Raven. Weak/scratchy transmissions on the ground as well as similar reports in the air on certain frequencies mostly at lower altitudes. 130 hours and 18 months on the plane and have been through a great deal of trouble shooting. Bigger ground plane, grounding the intercom to the remote comm checking the stamps on the unit to ensure the latest version, sending the unit to Dynon and bench testing etc. Next step is connecting an SWR bridge between the coax and comm unit.

Love the plane and the Skyview but this has been very frustrating not being able to communicate with ground control, tower or unicoms. They are also frustrated as well. The apprehension of not knowing on what frequency the problem will rear its ugly head is getting old . Hoping for answers.

Jim

Default Issue solved

I just wanted to update this in case it ever comes back up for someone else. After swapping antennae, swapping comms, msking new coax all several times to no avail, the last thing I did was make a new coax with soldered center pins and I have had no issues since. I can't explain why crimped center pins worked with other radios and other antennae and not the dynon, but that is the only thing that changed from crappy radio performance to great performance.

Interesting . . . how did you come on this solution? Luck? ( Luck is good BTW)

I tried it out of frustration. It was all I could think of. Still don't understand how the crimped connections worked perfectly with a handheld in the exact same coax and antenna installation and the dynon didn't, but it's working now.
