RE: SD-10G Range checking
How long is 30 steps for you? Range test in low-power mode with FHSS-1 receiver should be 80-100 feet. If you're getting less than that there are some things to check for.
FHSS3 is going to test longer and may not be affected by the same conditions as the FHSS1 equipment. So, putting in the one receiver to test against the other doesn't help much in terms of diagnosis as to a short range test on the FHSS1
Check these things.
1. Obstructions between the tx and rx antenna. Bench, tree, etc.
2. Try the test from a different angle from the airplane and see if it's the same range. Could indicate needing to move the antennas.
3. Are the antennas 1 foot off of the ground or more? A proper range test should have the antennas two feet off the ground. So put the plane on a table or stand perhaps?
4. Unplug all of the servos except 1, try again. Sometimes a servo that is starting to wear internally can give off extra interference that can in some cases shorted the range a little.
5. Make sure TX antenna is not pointed at the RX antenna
6. Make sure the RX battery is not low. Low voltage receiver battery/powersource can lead to lower range tests.
