swapped out the bearing, now much better

but where i had messed around with retraction setting some of my supports are not printing correct, but the surfaces are way better

#3dprint #ANET

so just discovered why my Anet A8 3d printer was producing rubbish prints all of a sudden

the X axis linear bearing had failed

so have replaced them and running a first print

seems better, no play in the hot end carriage now :)

don't you remember

"it all about the art of screwing up the deal"

and trump is a world class artist in that category

final print failed, looks like the temp was about 10deg C to hot as a lot of stringing, was a new reel of filament a brand i had used before so didn't do a temp test :(

will do a temp test tower in the morning then rerun print with lower temp

i have taken my FT991a apart to clean and check the connectors , which is which the value of the X6100 :)

my day job used to be computer workshop engineer, so used to taking expensive kit apart

my 3d printer was a kit form Anet A8, took me 2 days to build :)

you learn more when you break things !

M0PWX @m0pwx.bsky.social · 4d

managed to detach the swollen battery from the back plate

they are attached with pads similar to 3m command strips

i used a plastic ruler to gently prise the battery up, then a blunt pair of fine nose pliers, grabbed the adhesive and noticed if i pulled gently it seemed to gradually release :)

mine actually replaces the rear panel with the batteries
plan is to attach a battery pack (OEM or custom) on the rear of the new rear panel

so mine directs cooling across the PA and ATU board of the X6100, as opposed to cooling the outside of the case but not clearing the heat inside the radio

#Xiegu #X6100 #battery #3dprint

failed LiPo battery in my X6100

only the battery over the PA Transistor affected

heat is the main issues with the X6100

my solution is design and print a new back with 2 x 12v 25mm fans cooling the radio

i will run from 12v PSU and later work on the battery pack

blown LiPo battery in my Xiegu X6100

interesting only the battery over the PA Transistor affected

OpenSCAD design for replacement back plate for X6100

STL of new X6100 back plate imported into Cura to slice and generate the GCode for my 3D printer

#OFCOM #licensing #RSGB #GB2RS

Ofcom has implemented most changes for Phases 2 and 3.

Ofcom’s licensing portal can process applications for new M8/M9 call signs, more flexible Special Event call signs, also easier revalidation. It starts the move to single call signs.

Here's the latest on the UK contact that includes a HamTV test this Saturday.

The HamTV unit is scheduled to send "tone and bars" during the 08:15 UTC pass. Live video from the ISS will be attempted during the 09:51 UTC pass.

Watch ARISS social for updates!

The image shows ISS crew member Jonny Kim making a 2025 school contact via the ARISS Columbus Module radio. The event is a scheduled contact with the 1st Radford Semele Scout Group in Radford Semele, UK, on Saturday, 18 October 2025, at 09:51 UTC (5:51 AM ET). Jonny Kim will use the NA1SS callsign, and the ground station callsign is GB4RSS. The contact can be listened to on 145.800 MHz FM, with a live stream available at live.ARISS.org. HamTV testing will occur, and the cross-band voice repeater will be offline during the event.

i think if its the enforced move later, it was said the last 3 stay the same, so long as they are available for ease of admin

#ISS #SSTV #Series30

series 30 has been postponed due spacewalks

looking at mid November

M0PWX @m0pwx.bsky.social · 10d

at the same time i think the move to only holding 1 callsign (except for club / special event callsigns) comes into place as well

so i would lose my M7PGW and 2E0PWX calls, and remain with only my M0PWX

M0PWX @m0pwx.bsky.social · 10d

i though 2E0 / 2E1 can voluntarily move to M8/M9, but in another 18month'ish time they would be automatically re-assigned to M8/M9 and 2E0/2E1 revoked
2e0 > M8
2e1 > M9

last 3 letters stay the same
so 2E0ABC would become M8ABC

Our sleepy editor made a mistake on one of the time conversions this morning. All the UTC times are correct.

The correction is that the Columbus Module radio is expected to return at 4:20 AM ET which is 08:20 UTC. A corrected version of the graphic is below.

QMX Nano?

when was that announced and shown?
does it still have the achilles heal of the BS170 PA?

M0PWX @m0pwx.bsky.social · 12d

far cheaper per kill than missiles, save the SAM missiles for kaliber cruise missiles etc
