Just a quick little test.

Here's another angle of it.
The antenna connection is the SMB female inside that hole there.
Rather inconvenient.
The RX card also has SMB female, TX has SMB female as well, but on a pig tail cable and not soldered to the PCB directly.

A tiny bit dirty, but temporary RX connection I have in my Nokia ME59 while I'm modifying it to 23cm.
The TX side is going to be an annoying pile of work, essentially a complete rebuild.
The 5 stage PA designed in the eighties is going to be an absolute bear to drag from 900 MHz to 1297MHz.
So I don't think the BFR93A-> BLU98 -> BLV90-> BLV92 -> BLV94 stack will survive.
Replacing it in full or in part will likely happen.

YES!
Band is not gone.
Not back to it's former glory. but not some evil joke like 25mW EIRP limit or something.
But still very usable.
And unlike now, I should not have to buy back the band in 25kHz chunks if I want to operate on it.

ITU‑R Recommendation M.2164 on 23cm amateur service and RNSS operations now published in time for WRC-23 discussions | International Amateur Radio Union (IARU)

#1296MHz antenna improved.
Yesterday I got my hands on 2 pcs of about 20m long coax cable, 1/2", one with M+F N-connectors the other without connectors.
So today I had another amateur coming, and we did 3 improvements of the vertical antenna.:
- Increased height of the feed point a bit
- reduced cable loss by 6dB or more.
- The full antenna is now essentially free of the branches of a nearby tree.
Initial result: Improved signals locally due to less obstructions and cable loss.
I am happy.

#1296MHz
The plan is getting a preamp mounted near the antenna, and possibly also a 10W PA, so I can exploit the full 10W potential of the station.
As I am using my IC910 I intend to get a small horizontal antenna up, but need a rotator first. This antenna should of course also be with a preamp and possibly a 25W PA near the antenna. That should provide a decent system for 1296MHz.
#1296MHz
Past few days I have been working on getting operational with a X5000 vertical at my home, on 23cm.
The antenna is mounted quite low, and with a cable loss of 6-10dB (first test).
OZ7IGY (beacon) at 26km running a horizontal antenna is clearly audible despite being behind a hill.
A local QSO, (6km) was quite successful with 10W FM, and signals audible with minimum power out (<200mW).
Now more tests with other stations, and more improvements of the antenna system.

I share the documentation of the Gigantor 55 elements 1296 MHz 23cm antenna.

First measure of the Tonna 55 elem. 1.3GHz.
Perfect VSWR on ~1290 MHz, if the weather is nice I dismantle the antenna to redo the measurements outdoors in a free field.
