i tried this morning again and voila... it works again :-))) while being happy that i dont have to do a replacement, i still don't trust the situation 100%. explanation 1: i was too tired yesterday night and did things wrong. explanation 2: my unit has a strange behavior. as i don't like explanation...

yes, i connected the rfxcom to the rfreceiver program and tried all the options that worked ok during the last weeks. but at the moment not a single sensor reading over hours. i tried the hint from bert, to use a 17cm wire to simulate an antenna, again no effect. i ll give it a last try tomorrow. be...

hi, I just unplugged my rfxcom unit from the server and connected it to my desktop. i wondered why no signals were coming through. checked with rfreceiver. no sensor data coming in (I have about 10 sensors sending all time). looking at the led of the rfxcom, i can see a short green flash when connec...

rg58 is the ham's swiss army knife but it is not really 1st choice in the 70cm band. look a the attenuation on a 100m cable below. MHz AIRCELL7 ECOFLEX 10 AIRCOM PLUS ECOFLEX 15 RG 58 RG 213 432 14,1 dB 8,9 dB 8,2 dB 6,1 dB 33,2 dB 15,8 dB so rg58 is really poor performing. You can also increase sig...

I have a first bug fix release for the software available: http://www.pasternak.net/joomla/component/option,com_docman/task,doc_details/gid,41/Itemid,70/ Changelog: 10.7. Bug Fix Release v2.1 - fixed bug in syncing rf packet headers, better printout of unidentified data - added support for THN132N a...

I have a two new sensors connected to my rig. 1. THN132N This sensor sends data like the THWR288 with two differences: - packet length is 44 hex (sample 44ea4c203f8824808414) - bit #3 of byte #6 indicated negative temperature sign (I assume this is the same with the THWR 288) 2. THGN122N This sensor...

the software did record 24h of sensor data without hick up, so i think i can release it for download. building weather graphs also works ok, so here we go... http://www.pasternak.net/joomla/component/option,com_docman/task,doc_details/gid,40/Itemid,70/ if you find bugs/errors, please let me know. as...

@bwired: the uv138 got some serious rain during the last two days. it is still working... we 'll see ;-) when doing my first tests with the rfreceiver i got a temperature signal that looks like from outside (based on the value) but was not part of my wmr928 rig. looking around the house i found a se...

HI, i just had a look at the error log of my sw. beside other things i get information about records that cannot be decoded so far. there i found the following entries: wmr928d: unidentified byte sequence: 44 ea 7c 10 80 40 90 4d 14 14 wmr928d: unidentified byte sequence: 44 ea 7c 10 80 90 d0 aa 94 ...

during the last weeks i adapted my linux sw (written in plain c) that reads weather data from the oregon wmr928 to directly read sensor data via the rfxcom receiver. The advantage of this approach is, that you can now use as many sensors as you like (actually, i limited it to 10 of each type) and yo...

inpecting the rfreceiver source code did help. uv138 is checksummed by the following code: Function checksumw() As Byte Dim cs As Byte cs = (recbuf(0) >> 4 And &HF) + (recbuf(0) And &HF) cs += (recbuf(1) >> 4 And &HF) + (recbuf(1) And &HF) cs += (recbuf(2) >> 4 And &HF) + (recbuf...

hi, i do have problems in getting the checksum right with the sensor data on my uv138 sensor. the incoming data is: 0. 78 (record length in bits = 15 bytes) 1. ea (sensor id, high byte) 2. 7c (sensor id, low byte) 3. 10 4. 80 5. 30 6. 40 7. fe (high nibble is checksumw2 = f) 8. 43 (low nibble is che...

Many thanks to Bert who gave me the hint to install .net framework 3.0 on my windows machine. Having that I could start RFreceiver and after switching to "variable length mode" I can see all the weather data coming in. GREAT! My problems with linux look like the ftdi module included into m...

Hi, I am brand new to the rfxcom and do have a problem in getting it to read out my oregon weather sensors. 1. I am working on linux (old 2.4.20 kernel) 2. the rfxcom device seems to be properly addressed at /dev/ttyUSB0 3. I set the transfer protocol to 4800 baud, no parity, 1 stop bit. Here are th...
