[teqc] How are -O.rt and -max_rx_SVs options related?

Dear all,

I have noticed that our data are missing many epochs when rinex files are created with a config file that contains the "-O.rt " option to define receiver type.

[elidana at hutl16534 local]$ teqc -tr d -O.rt "TRIMBLE NETR9" WARK201902090800a.tgd > tmp

When the -O.rt option is removed from the config file, rinex files are complete.

[elidana at hutl16534 local]$ teqc -tr d WARK201902090800a.tgd > tmp
? Error ? translation of 'WARK201902090800a.tgd' may have started with GPS week 2041 rather than 2039
(try using '-week 2039' option)


If I want to include the -O.rt option in our rinex generation proceses, then I have to include the -max_rx_SVs option as well to ensure no epochs are missing.

[elidana at hutl16534 local]$ teqc -tr d  -O.rt "TRIMBLE NETR9" -max_rx_SVs 64 WARK201902090800a.tgd > tmp
? Error ? translation of 'WARK201902090800a.tgd' may have started with GPS week 2041 rather than 2039
(try using '-week 2039' option)


The same issue is occurring with the 2018 December and 2019 February releases, and I've tried the statically linked CentOs and RedHat distributions.

elidana at hutl16534 local]$ teqc -version
executable:  teqc
version:     teqc  2019Feb12
build:       Linux 2.4.21-27.ELsmp|Opteron|gcc -static|Linux 64|=+


A sample input file is saved at the following link:

So I guess my question is: what is the "recommended" set of configuration we shall use?

Thanks in advance!
