2m Net NARS – Tuesday Evening

So, it was the evening of the last NARS 2m net in 2015. I headed to the highpoint in Catsash again, some 600+ft ASL. The Newport Amateur Radio Society net was due to start at 8pm on 145.375. I could hear other stations on frequency on the way, and when I arrived at the highpoint other stations were booming in 5/5-5/9+. I was running 50 watts, through a NR7900 diamond antenna, from a Kenwood TM-D710GE.

I made contact with G0IUE (Jon) on frequency, at around 7:55pm and we had a short QSO. I politely asked if he could instruct any NARS members arriving on frequency to QSY to 145.400. Jon was a good 5/9 from the Chippenham District Amateur Radio Society, and it transpired this was their yearly Christmas/New Year net.

We moved to 145.400 and were joined on frequency (in rough order of appearance) by :

2W0ODS – Dale – Dale was holding fort on 145.400 ready for the members to call in. His location Ridgway, Newport, and was a strong 5/9 with me, although I could move 12-20 inches in the Landrover, and he would drop to 3/1, amazing phasing conditions. When Dale headed to his mums at the end of the net he was still 5/9 with me.

MW0OPY – Doug – Doug was a great signal to me, even on 10w, 5/9 all the way from close to Bassaleg. I think he was using a beam, generally pointing East.

GW4SUE – Margaret – Margaret also a great signal on the old Yaesu 227 Memorizer at 10 watts. 5/9 throughout the evening without variation.

GW4BLE – Steve – Grandad Steve, or is it Grampy, Gramps, Grancha ? 🙂  Great signal from his station, 5/9 no issues what so ever. He noticed a reduction in current draw, so perhaps an swr issue related to water ingress perhaps?

GW3NWS – Ross – Ross was woken from a nap by a phone call from Doug. He tells us that Holby City sent him to sleep. Great to hear Ross on, and a booming signal from his antenna that touches the stars. 5/9 endstop.

GW4OGO – Steve – Steve arrived on air, and we should now call Ross, Ross Clarevoyant (clairvoyant), as he passed it over to OGO without knowing he wasn’t on air. It so happened, that Steve had turned on that very moment. Spooky indeed !!! Strange goings on with signals from BLE to OGO on 2m, and perhaps a slight issue at both stations, who knows.

GW4TPG – Martin – Great to hear Martin on frequency. I had to move the truck a couple of feet to phase him in. He was 1/0, and then 5/3 within a few feet, so quite amazing. We had a quick qso to get us in each others log, but I had a fat finger moment, and half of my over went to another frequency…. eeek.

After the net ended around 9:30 or was it 9:40, I moved to the calling channel,  but no luck there. I then repeater hopped and put a call in through GB3DR (about 70 miles away, and an S9 signal) at around 9:50pm. G0JLA came back to me, Dennis, from Weymouth, on the south cost. We had a good natter for nearly 40-50 mins and were also joined by 2E0BWK/M, Kevin, from Peasdown, Bath, who was down from Harrogate visiting family.

I did a couple of tests with Dennis, and was able to get into GB3DR on 5 watts from the high point in Catsash, the audio his end not really much different. Unfortunately we couldn’t achieve simplex.

The winds were starting to build as storm Frank approached, and I headed down to the home QTH around 10:45pm.

Cwmbran 2m Net – Monday Night

Well, after the over indulgence of Christmas, it was time for another 2m net on 145.375. I headed out in the Landrover to Catsash, my local highpoint some 600ft above sea level, within 10 mins drive of my front door.

Whilst driving there I could hear GW4YNP coming through GB3RT, but my receive signal was in and out, so I didn’t go back to him.

I got set up around 7:25pm at the top of Caelicken Lane, where it joins Coed Y Caerau Lane. MW0LUK/M was first to check in on GB3RT. He was having difficulties keeping GB3RT open from his location, and I was listening to his overs on the input with quite a strong signal to me. We moved to 145.375 simplex around 7:30pm.

The stations that arrived on frequency in order of appearance :

MW0LUK/M – Chris – Now stationary mobile in a lay by close to McDonalds on the A442 heading towards Abbergaveny. A great signal to me, 57/59 with some slight qsb. We had a good chat for about 20 minutes and we were able to stay in contact whilst he drove to Little Mill, even when Chris was sitting outside his garage at home. Good stuff. He even had his own light show, with his neighbours outside light turning on and off with each key 🙂

GW0OAJ – John – Arrived on show just as Chris was signing, but John was unable to copy Chris at all. John was a 5/9 no problem as expected.

GW4SUE – Margaret – Popped in about 5 mins after John showed, she thought it was the night for the Newport net on the same frequency, and it was great to hear her. She was a day early 😉 A great signal from Margaret over in Maesglass, from her 1981 Yaesu 227 memoriser (is that with an s or z?) at 10 Watts. 5/9 all through the evening.

2W0OGY – Chris – Called in around 8pm give or take, and was great to hear him on frequency. Concerns over the upcoming Frank storm were raised and possible damage to HF wire antennas shrugged off as ‘ah well’. Chris’ signal 5/6 5/7 no problem, to me at 600+ft ASL.

Chris and John said their farewells and I was about to QSY to the calling channel around 8:45pm and we were then joined by :

GW3NWS – Ross – Popped in to say hi, and had a natter with Margaret and myself for about another 15 or so minutes. Fantastic signal as always from Ross on his ‘white stick’ 5/9+++ no doubt at my end.

Around 9:10pm I hopped down to 145.275 to see if the usual suspects were on frequency, but was called back by 2E0BWK/M, Kevin, Peasdown, Bath. He was down south (home qth Harrogate) visiting family for a few days and was playing a bit of radio. We had a chat for a good 10 mins or so. His signal 5/6 with me from his mobile station/static. Good stuff, and safe journey Kev back home later in the week.

I decided to go QRT after that as it was approaching 9:30pm and headed home back to Magor.

2W0LGE – New Callsign

Yay !!! after passing the exam on the 20th November, it has been a long wait, but finally I have my new Intermediate callsign :

2W0LGE

A couple of contacts this morning to warm the sign up, and many more to follow I am sure.

All the best

50 ohm Dummy load – on the cheap

Well, I decided I needed a dummy load. I ordered a bunch of 3w @ 510 Ω to put in parallel, so roughly 30W handling (perhaps more with the added cooling for short periods).

So, 10 of them soldered up to some scraps of vero, and a reading of 50.6 ohms taken, so all is good on that front.

solder_weld

I added the so236 to the tin lid, and solder/welded it all up. It will be sitting in a Golden Syrup tin, with a 500+ml of mineral oil. I had to silicone around the underside of the so239 to prevent the oil from oozing up through the connector.

Ah, job done, and a total cost of less than £8 🙂

Intermediate Exam – Passed

Well great news, both myself and Dale (MW6FNV) passed our intermediate exams with flying colours this evening with Newport Amateur Radio Society.

Really looking forward to the new facilities the license provides and the increased power.

Many thanks to Ross (GW3NWS) and John (GW0OAJ) for the expert tuition.

Two down, one to go !!!

CADARS 2m Net Monday Evening

Well last night was interesting. The fog was descending in Magor, but I headed up to the high point at around 7:35pm on the top of Ridgeway, Newport. Dale (MW6FNV) was due to join me a bit later on. It was very foggy up there when I arrived, and turned the radio on and dialled into 145.375 on one VFO and GB3RT (433.000 listen) on the other vfo. The Kenwood TM-D710GE in the truck, with the Diamond NR-7900 mobile antenna, 10 watts.

A call was put out on 2m 375 but nothing heard, I glanced at the other vfo and noticed an S3/4 signal, but the squelch was not opening as it was looking for 94.8. So I had a listen by turning the tone squelch off my end and to my astonishment I could hear GB3CK, on the same frequencies as GB3RT, but a different access tone !  This repeater some 165 miles away, belonging to the Kent Repeater Group. It is located on the hills above Charing in Kent, just this side of Canterbury.

gb3ck

I listened for a while, and the signal was hovering around an S3-S5 so some QSB on the frequency. I decided to put a call in after scanning for the tone (103.5) and I got through. I had a chat with two stations, mother and son. MW6GVZ, Jill, based in Sevenoaks (or is it one oak these days?), and 2E0KJJ, her son Jeremy, based in Canterbury. It transpired that Jeremy was attending the University of Kent at Canterbury, the same uni I went to, some 20 years ago, a small world indeed. We had a quick qso, but fearful of conditions dropping out I said my 73 and listened in for another 5-10 mins, at which point they started dropping down to S1. I was using legal limit power output of 10w from the Kenwood TM-D710GE radio into the Diamond NR-7900 mobile antenna. Fantastic conditions indeed. Their signals were both quality 5, and the repeater giving me S4/S5.

Listening around other repeaters all sorts of stations and signals were being heard, so there did seem to be interesting conditions.

I put another call in on 375 after the excitement of the distant repeater QSO, with power now set to 5w, worried that my signal would be interfering with all sorts. Jim came up (MW6MUN) and Ian (GW8CRH), both 5/9 on the input. Chris (MW6LUK) showed up for a brief 10 seconds, but I gather from a background conversation he was called away, his signal 5/8 on the input (yes I did check even with the short transmission). Nigel (GW7SSN) also popped in to say hi and let us know what he was doing better. Get well soon Nigel !!! His signal another 5/9 on the input.

Sometime later, around 8:40pm Pete (MW0RPB/A), Chris (2W0OGY/M) and Ken (MW0YAC/A) came on briefly to say hi, all great signals, all 5/9 on the input. Pete and Ken enjoying a brew at the Dorallt and Chris on his way home in the car.

I stayed up there for an hour or so after, but wasn’t really in the mood for playing radio as I was rather tired and headed home around 10:20pm ish.

Good stuff indeed !

Quick trip to Twmbarlwm

Another trip to Twmbarlwm yesterday, as I was out in Rogerstone on business. On the way back, a short detour into McD’s and then up to the top for an hour or so on the VHF/UHF rig.

Chatted to RQM (Dave), FNV (Dale) and OGY (Chris) on 145.375. A nice couple of hours out of the way of the hustle, bustle, and noise of Newport. The X50 collinear sat on 3m of fibreglass pole, cable tied to the fence post.

X10 to CBus conversion – Part 1

My mum’s house has a rather old (some 8+ years) X10 install, which was showing signs of needing to be replaced. The alarm system was also having a few issues, so we decided to strip it all out and start again !  There are some 79 X10 modules, which consist of dimmers and relays. The alarm has 48 zones and is a Cytech Comfort system.

A decision was made to invest in CBus 2 and Cytech Comfort 2. We would be running LED bulbs on the CBus system, so an investigation process was undertaken to find suitable compatible bulbs with CBus (yes no one could tell us what to buy). I tested about 6 makes, and MegaMan were the ones to go for. Smooth dimming and no flicker. They worked great ! Mum decided that she wanted Daylight temperature led bulbs, some 6500k. The bungalow has always been quite dark inside, so this might be a welcome change.

So, time to rip it all out ! The old wiring mess :

x10

I ripped all this out with the help of my brother (Julian) and labelled up every wire. Roughly 150 twin and earths. Half of them were pulled up through into the attic space as they are not being used in the new system. These redundant wires were from momentary switches to turn the x10 modules on and off, essentially the light switches in each room. The new CBus system works on a low voltage over Cat5 network (star, bus) to communicate with the wall switches in each room and our father who built the bungalow ran Cat5 to each light switch for future proofing.

So, we starting making a mess !!!

 IMG_3023 IMG_3018

So a plan was formed, and the first CBus modules was installed. Each module has 8 x 1amp dimmable lighting channels.

IMG_3024

Slow progress was made, routing wires and ensuring all labelling was accurate.  There will eventually be some 32 lighting circuits to different rooms and areas around the bungalow, and 12 x 10 amp relay circuits for items such as pond pumps, cabinet low voltage lighting, bath room fans and other such loads that do not require a variable supply, but one that is off/on.

So after a few days the chaos started to take shape…

IMG_3053

IMG_3052

Each dimmer channel goes through a 1 amp MCB, and each relay module has a 6 amp MCB protecting it. At the end of the channels we are running various MEGAMAN led light bulbs.

The next post sometime later this week will see the lighting system completed, and a start on the Alarm system will begin next week.

Cheers !

PS: no blue smoke has been released in the change, and mum loves her new daylight bulbs and touch sensitive switches.

Kenwood TM-D710GE Update

Well, the new one just arrived from ML&S, and it is like night and day. What a difference, fantastic job.   The mod involves moving that 0 ohm surface mount resistor from PAD 0 (the right one in the image) to PAD 2 (the left one in the image). This enables wide band, and cross band repeat.

Thanks to ML&S who did a great deal on it, arrived early next day, and top quality soldering and mod work !!!! I am well happy 🙂
