I found a lovely location for #hamradio #UHF and #SHF #microwave beacons.
The current #meshcore repeater up there is too boring.I like the #Q65 style of british repeaters ( #gb3mhz #23cm occasionally comes in range for me ).
rfzero.net might only have pcb for baseband but no info on frequency multiplications and PA.
w1ghz website is informative.
A standard Pi Zero 2 + UHF HAT might be consume too much for solar + battery as I do not want to ask/pay for energy up there.
Hints welcome!

In case you needed another reason to get a Quansheng, a 23cm (1.2 GHz) transverter!

A very successful open day. Our #QO100 station worked Brazil, France and South Wales. An interesting experience where stations in such different locations are all the same signal strength.
Jake worked a few stations on the #23cm band, the furthest was in Gayton, Northamptonshire.
Ian worked Spain and Poland on #6m and some locals on #4m with a dual band Yagi.
North Wales Amateur Radio Group had fun on #2m and Wirral Peninsula amateur radio club were active on #HF.

@vk2bea In IARU R1, the band 1240 to 1300 MHz is assigned to amateurs ("the 23 cm band"). I have never used this band. How much interference do hams receive from Galileo, Beidu or QZSS satellites?

Ob das eine gute Idee war? Starker Regen mit Gewitter. #durcontest #hamradio #23cm

I am looking for slot aerial designs in metric sizes.
Some stl files for a cnc would be even better.

Yesterday's #SOTA activation - Moel y Gamelin.
I tried out the new tripod idea for the antenna mast. It needs a guy line or two, which should be sorted for next time.
It was very cold and windy, so I didn't take many pictures at all. 9 QSOs on 23cms though, which was very good!In time, when we get warmer and more pleasant weather, I fully intend on making videos of my experiences using the Icom IC-905 for SOTA and other portable operations. #AmateurRadio #HamRadio #IC905 #23CM #Microwave

Is the IC-905 an ideal SOTA radio? No. But you can absolutely do a #SOTA activation with one, and I'll do it again. Many times. This was the summit of Penycloddiau today (GW/NW-054). Wx snowy but not much wind, so it wasn't too bad. Thanks to my good friend @DafyddJack and 4-legged companion for the company #AmateurRadio #HamRadio #Portable #icom #2m #23cm #SSB #VHF #UHF

Just a quick little test.

Last week, I activated the #SOTA summit of Moel Gyw. This time I was going to give #23cm a proper go and I could see a few others had similar plans.
Armed with my FT-857, SG-Lab transverter, loads of suncream and no idea on how I was going to connect and mount the gear when I got there, I set off.
Parking was a pain, and it took some trial and error at the top, but I made 9 QSOs on 23cm with the PCB antenna and 2w! After that, I moved to #2m which was good fun as usual. #HamRadio #AmateurRadio -

Hamfest packet radio goodie.
Suspected to be from the former Finnish packet radio network.
1200baud 1200MHz band backhaul link with TAPR TNC-2 clone. -
I’m currently working with the #DM7A team from JO60OM (Hirtstein in the #OreMountains) in the #DARC #vhf #uhf #shf #contest - we are #QRV on #2m #70cm #23cm and up. There is still plenty of time to work us. Just ask for a #sked on ON4KST #chat. The weather is getting better again… #HamRadio #Amateurfunk #ssb #cw #S07 #iaru

This photo was taken with great anticipation, just before finding out that a log periodic antenna, an SG-Lab 23cm transverter and a SOTA summit aren't a good combination.
Strong out of band signals (probably mobile phone networks) meant full scale QRM unless I pointed it away from any populated areas.
This was Shining Tor and my 1st 23cms activation. Disappointing, but 2m FM proved reliable as expected with over 25 QSOs before getting too cold. #AmateurRadio #hamr #HamRadio #SOTA #23cm

New #Quansheng announced.
10m/6m/2m/70cm Quadband with 0.5 - 1160MHz wide receive. AMF/FM/SSB receive and likely only FM TX, like usual.
Also 6m/2m/70cm tribander with the same wide RX.
Sadly no #23cm even on receive.
Will be interesting to see what price point these end up on.

Hab mal die Fotobox angeworfen und eigene Produktbilder angefertigt.

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. -

Planung für ein zweites 23cm Relais. Die Geräte sind schon mal da. Standort wäre sehr exponiert bei DB0PUC.

Neue Überwachung hinzugefügt. Nun wird die Temperatur der 23cm Endstufe überwacht. Überschreitet die einen Wert wird die Endstufe stromlos geschaltet. Sollten die Lüfter ausfallen, geht nichts kaputt. Es ist fantastisch was man mit NodeRED und MQTT alles damit schalten und überwachen kann. Sollte der Grenzwert der Temperatur überschritten werden, werde ich ebenfalls informiert über einen Notification Channel.
