Hello Hans, Perfect, a hex file is fine, I have blanks and can burn one here, that's very good of you!! chris AT chriswilson DOT tv All the best, don't burn yourself out :) Monday, June 12, 2017 --

no pictures from this launch , thay all look the same, here is some pic:s from BSS5 prep and launch, ?BSS5 (

Hi Chris I have an awful lot of things going on at the moment, QRP Labs product developments etc.., and I have not had a chance to finish off the v3.13 firmware. I think the best solution will be for

Hi Camille You are right, the firmware document is inconsistent with itself. I have now amended the diagram in section 3.1 to show a jumper across the switch which causes the ProgRock firmware to

The S25 Balloon woke from the dead and is now 7 or 8 degrees from the north pole. Spots are very thin from the top of the world but this time of the year the sun shines all night.

Very good work Mikael, Perhaps I missed it but do you have any pictures of your balloon? John K5MO

Hi, I have understood that, when relay-switched LPF kit is in use (is?plugged, with LPF kit in?place?"1") the RF out?can be accessed from multiple locations?on the relay-switched LPF kit board.

Hello Ivan. That's good to hear that you've got it to TX now. I use a very sharp craft knife to scrape the enamel off the wire. This seems to work much better than emery cloth or sand paper. Place the

Uh-oh . . . Balloon 100 vs Telemetry 98 . . . pretty good result Mikael. If the track were straightish that'd be 40,000 k in 528 hours, so 75 k/hr but really over 100 k/hr for a convoluted track.

BSS6 never checked in yesterday, most likely marks the end of this flight, lots off new personal bests, duration over 22 days, altitude record -10800m, distance traveled, moste likle crossing of

Thank you all again for the comments. We resoldered the low pass filter toroids. They seemed very problematic as the wire would not allow to be tinned even after we tried some sand paper. I think we

Hi Hans, Thanks for the info. It makes sense now. I thought there was some conflict going on, but I found the controls to the 5W PA raised cosine circuit were very sensitive to RF and earth loops,

Hello David, I was given an unbuilt kit by a friend and I have a box with a translucent lid that would be ideal to mount a board in, then I realised it would take 2 boards, just perfectly... One for

Thanks Hans. Reading paragraph 3.1 page 5 throws me into confusion : "...then you do not need to fit ...." . 73 de Camille . F4IBA.

Hans, I can live with the two clock option. What would be nice was the ability to copy Clk0 to Clk1. I am a skilled ATmega programmer and the ATmeaga 238 is probably my favorite chip. Bob Macklin

Hi Doug Thanks for the info and the amazing photo. Great location! The wavelength of GPS is something around 18cm. I guess is sneaks in through the cracks along the door of your container. Still

Hi Ken I'm sorry, I owe you several emails, I know. I'm getting there... The Ultimate3S packs a lot of functionality now, in that processor... and there are some pins which are necessarily shared

Hi Bob The Clk0 output is rotary encoder tuned. The Clk1 output is set to a fixed (configurable) value. Clk2 is not available, it is used for frequency counting when GPS discipline is used. In the

Hi Camille On page 1 of the operation manual for ProgRock it explains that the serial programming mode is only enabled if the 4-way DIP switch is in a certain configuration. If you have not fitted the

I have some questions about the QRPlabs VFO. I would like to use one with a transceiver. I would like to use the output that is tuned by the encoder for the receiver LO. I would like to use one of the
