Considering a radio

Considering the TH-9800 (4m version) from Sinotel. Looks perfect for Raynet stuff.

Diplexer plans: Make yourself a diplexer courtesy VK3ZAV

Questions posed to the vendor:

1. Recommend a diplexer to split the 2m+70cm side from the 4m side
2. Recommend a diplexer to split 2m and 70cm – assuming the rig can’t handle this itself
3. Can the cross-band repeat function be locked down to only transmit on receipt of a specific CTCSS tone?
4. Can the TX power be set independently on the two sides of the radio?

New radio for me, if they come back with the right answers…
