Well I've been bouncing around looking for anything that might be a culprit or at least reduce the hiccups in transmission. I'm beginning to think that Pure signal maybe involved is some way. The reason I say this is that under the conditions that I am testing (two tone on pure signal on with ~ 12 w...

A few months onward and I've gotten around to a few more tests. Using a separate receiver I've been doing some more low power tests (10 ~ 15 Watts) in transmit variously in voice, tune, and 2tone. The hiccup has been happening in all of them with PS on or off not making much difference. From the rec...

Don't think so I'm a bit OCD about that. I've installed ferrite cores on all of the supply leads (AC and DC). A ferrite core between the rig output and the amp. And a ferrite core on the amp to rig feedback line. Nothing on the amp output...........but thats a 1 metre double screened coax into the d...

Hi to the group, I've been working at slowly reducing the latency of my audio in Tx and have reached a point where I have what it consider to be a "nice" stable setup. So I only get buffer over/under flows every few 10's of minutes (and usually when the system over all cpu useage "bli...

Rob, you are quite correct, I can and do make it work. My amp is a Ldmos type and I have been warned....don't over drive it !!! I use a Midi device with slider to set the drive levels with 30 watts of drive giving me ~900 Watt of output from the Amp (theres a 10 db attenuator in the amp input to hel...

Ok thanks for that Scott. Drat! I would have preferred to have screwed up somewhere.
Where do I apply to have this added to the ever growing list of wants and wishes.

Regards Bob

I'm not sure if I'm missing something (as usual) or the PA profile is still work in progress. I use barefoot operation (100 Watts) and Amp ( 30 Watts out of the rig 7000mkII) and have set up two PA scaling profiles ( bare foot and Amp) with all of the scaling and offsets done. They appear in white a...

Got it thanks !

Regards Bob

Thanks I will try that

Hi, before I go in hot and heavy and reload everything....has anyone had any issues with AM and SAM. Either I've done something silly with my setup but, when I decided to try and listen to an AM signal....no audio ditto SAM. DSB works as does everything else. And no output if I try and transmit. I'm...

Ok update and closure on the topic. One I have got into the amp Tx O/P before the antenna output switch with a neg 50db tap off, so I can now put all antenna connections through the amplifier, with the amp selecting the antenna output by frequency. Two removing the matcher on my long wire. Adding a ...

Agreed Scott, sadly that will have to wait for a while...for the next combined Christmas and birthday wish maybe. The Amp blew my piggy bank for a while.

Regards Bob

Yes I have a 20Metres and up hexbeam that I can use QRO and a long wire that is matched with an auto tuner. The only other solution that I have thought of, would be to do the switching after the rig. That would work as I can run PS down to ~10 watts, but don't have a switch rated to 1kW at the momen...

I would like to know if I can access the "Rxbypass on Tx" on midi. Currently trawling through the list for my MP3e2 MIDI I don't see anything that looks right. For me at the moment, I only use my amp and its external PS feedback on certain bands and one antenna input and find that I keep h...

Ok will give it a go. question does Thetis use the two digital inputs to the 7000 ?

Regards Bob VK4BXI

Hi all, first Homage to Ritchie and co, wow you guys blow me away. I run mixed barefoot and amp and have my external feedback organised nicely etc. Problem is when I run my amp the rig output is scaled down to 25 watts max. so I really need twosets of PA scaling options. (I really don't want to blow...

Thanks, the main reason for looking at a 10 db coupler was that I have 100 watt 50 ohm chips already. Making a 100watt 10 db attenuator would be a challange and buying one would be ~ $ OZ 100 from the US. So the thought of a coupler was tempting.

Bob

Thanks for the reply. Yes the amp is available as a kit .....but I am buying it as a fully finished box so I need to investigate further. Clearly the best position is inside amp .....but the amp does have input power overload protection so not so easy. One thought is to have the 10db attenuator in l...

yes that looks exactly like the one that I purchased.

regards Bob

Not quite sure these days. I was told I had a good machine......but in relation to what ?



But this is what I have.

Regards Bob

Nick you are most welcome. I used a "Ukraine" transvertor. This had buttons to switch to switch from 2M to 70CM and to change the Lo frequency up by 2 MHz to help band coverage. All worked very well ......as advertised with exellent noise and sensitivity. As above you don't need to use the...

Hi with my sons help I found the HP monitor software and took this shot of RX! and RX2 on

The video cards don't look to be the problem.
also looked at the network transfer rate RX1 only ~80Mbyte/second add RX2 it goes to ~150 Mbyte/sec.

Regards Bob

Thanks Richie....in anticipation. I took my gauge of the pixels being used by the display in the bottom left. I'm running double the frequency coverage of the 768kHz..... 1536 kHz.... I suspect that maybe where I'm running into trouble. I went there because I'm also using the 7000 with a 2 and 70 CM...

Thanks Richie, Ok it looks like I am pushing my luck here, and not just fighting a windows setting. I will try to lay hands on a serious gaming video card and see how I go with that. But even if I'm out of luck there 20 frames /sec is still not bad. Having 2 27" curved screens showing the whole...

Hi all, I have had the spectral lights (the red and yellow ones on the top left hand corner of the screen) turned on for a while. They flash at me and I've been trying to optimise my setup to get the maximum screen update rate without getting regular flashing from them. I run a moderately fast HP I ...

Hi all, I'm about to purchase 1kW Lmos amp. The amp only requires 3~5 watts for full output so I want to use ~50 watts out of my 7000 mkII to achieve that. That requires a hi power attenuator of ~ 10 db. I have several 100 watt 50 ohm "chip" type load resistors available but no other high ...

Hi I'm not quite sure where this belongs but since its with my transvertor I'll start here, I'm using a 2 metre / 70 CM transvertor running with my 7000mkII running the latest MWOLGE 21k8 and the latest P2 v2.18. When working with the local repeaters I get quite alot of "splatter" (my word...

Yes that fixed it !!! thank you very much Richie ! :D there was a value of 5000 in the line that you indicated....I set that to zero and bingo. I didn't go anywhere outside of the program to get into this state, but I was playing with the memory settings to store a couple of local repeaters. That is...

Not nice but I was working installing transvertor setups for 2M and 70CM then after several hours I found that I could not switch between the two bands. I switched everything off and rebooted. Then I find that I have a fatal flaw !........see below. It now won't let me boot thetis. Machine is a blac...

US dollars
