Lmst

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

A map of the Qsos made. All are 23cm band. Most are to the greater Manchester and Lancashire area and a few are around the Stoke on Trent area.

A picture of me attaching a small log periodic antenna (for 23cms and 13cms) to a small fibreglass mast, supported by a tripod. In the background, views of green fields and hills are present. The sky is blue with white fluffy clouds. It looks warm but I'm wearing a coat and hat (because it was actually very cold)

A picture of the telescopic fibreglass mast (collapsed) supported by the tripod. The Icom IC-905 RF unit is mounted to the mast below the top of the tripod.

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

Soo, bin wieder #qrv auf #23cm , #70cm und #2meter . Kabel und Stecker neu, Anpassung der zwei Meter yagi erneuert. Der Mast ist an einem anderen Standort und kann jetzt von einer Person umgelegt werden.

Just a quick little test.

Some new (to me) antennas :)

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

A coax cable with crocodile clips is attached to a driven element of a 3 element 2m yagi (SOTABEAM). The braid has almost totally disconnected from the crocodile clip, only holding on by two strands.

A trig point (painted white) has a fibreglass mast tied to it, with a radio sat on the top of the trig point. A messy run of cables runs up the mast to a metal box, with a yellow antenna attached to it. This is the SG-lab transverter with 2 element PCB antenna. The transverter is held to the mast using a velcro strap. This is as dodgy as it sounds.

Alternative view of the trig point with the Yaesu FT-857 clearly in view. The fibreglass mast is behind the radio. The messy cables running up the mast to the SG-Lab transverter probably looks even worse than the other photo. The transverter (silver metal box) and PCB antenna are visible at the top of the photo.

The radio used in this link is/was an Icom IC-12GAT.

1Watt, 1240-1300 MHz.

#23cm #icom #hamradio #packet

Black Icom IC-12GAT handheld radio bolted down to the chassis.
It''s antenna output going to a type-N flange mount connector via a black coax cable jumper.

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

A car, a couple of garages and amateur radio yagi antennas in front of trees.

A trailer with amateur radio antennas for super high frequency bands.

A parking lot with a couple of cars, a house and lots of rain in the night.

Our 23cm Yagi is finally on the main mast with decent coax and a rotator. This has been on the to-do list for a long time. #23cm #AmateurRadio #HamRadio #hamr

A tall mast with a vertical antenna on top and just below, a 23cm band yagi. The sky is blue and there are trees visible at the bottom of the picture

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

Views of a stone wall on a summit. You can see other hills in the background. In the foreground, a fibreglass pole is strapped to a gatepost. At the top of the pole, a small log periodic antenna is mounted in vertical polarisation. The antenna is encased inside white plastic to protect the thin metal interior (which isn't visible).

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.

Nokia-Mobira ME59

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.
#23cm #hamradio #1296MHz #Mobira

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.
