I find it annoying that lots of the American HT's don't support cross-band channels. For sure, not the new Icoms, don't think the TH-F6, but all Chinese radios I have played with will do split band channels.

My FT-530 most certainly does true full duplex on mode B and mode J. You must be misinformed on the features of these HT's.

Even the $30 Baofengs support cross-band memories for sat operations. That's how I started, but as Paul said, half-duplex on FM should not be condoned now, especially as our FM birds get more and more crowded and it becomes just an additional source of QRM.
I've been very happy with my D72A. Packet is a nice feature to have to work ISS and NO-84.

You are simply wrong. The Kenwood TH-D72, D7, D7(G) as well as the Yaesu FT-470 and FT-530 all are excellent full-duplex HTs with no desense.
It appears you are suggesting that people operate half-duplex. That can work somewhat, but is definitely not something I would ever recommend.

Nest shoot for - What dual-band HT can program SAT offsets (in the SAME single memory)? My definition: in one memory can program both 2m-RX AND 70cm-PTT or vice-versa. Why: you only need say 4 or 5 memories per SAT for AOS/LOS OPs - one

via
PC Program. Kwood TH-F6, Icom IC-91/T8, Alinco G7 cannot they can do it only via flipping the A/B Bands (pain in the butt) - they do not allow cross band offsets in memory.
Now another BAD issue with Yeasu & Wuoxun is they both have a high discharge rate of battery when in the OFF state. I found if I leave my
HT's
on the shelf for +60days I must isolate the battery for the radio to eliminate wasteful discharging dropp[ing a B-Meter bar. I do this by
using
a 'paper' business-card cut it to size, sandwich between the battery and
HT
- isolating the battery contacts. Easy, simple, effective, cheap - what
HAM
Radio is all about.
