Hi Terry   Scot Teller I think has a web sight under his name that should help also last years around May or June in QST there is a good article ans how to . If you can"t find it there let me know and I will see what I can come up with .  73 KE7UGT Rick

Terry, Are you looking for something in particular? As I just did a google search and came up with all kinds of home brew interfaces. The hard part is deciding on which one to try. I use a Rigblaster and have not built one therefore I do not have a preference of one design over another. But after doing the google search I am now wondering if I should not give it a try, my skills are not the best but that has not stopped me in the past.

HI terry I was wrong its Skip Teller KH6TY  he is great and I have talked to him several times the will take the time for packet radio.TNC X costs about 50 dollars for the kit and it works great just an idea but Skip can get you going I'm sure . He wrote a Nifty guide for PSK 31 which I think every body should get it will save you lots of time and I think you can get them though the Nifty web site. Hope I helped .73 Rick KE7UGT

hello again

thanks for the info

we have a problem with importing anything from the usa costing more than £18 = $12 .

uk customs requires as much admin as a commercial company and charges a disproportionate amount in fees and duties

so unless he has a uk agent ( ie a commercial company)it is virtually impossible to buy.

there may be a uk based kit provider but otherwise i will have brew it myself

what is the nifty web site. i will try a google search

thanks for your help

Hi Terry Nifty is a company that sells inexpensive manuals  that show an easier way of setting up your radio. I have for example an FT60R hand held that is a great radio except the instruction manual is hard to understand so Nifty is a good choice.Now they added another type of helper PSK it makes digital very simple.Did you get ahold of KH6TY he wrote the book so there you are . Happy New Year  Rick ke7ugt. One more thing at about 1400 to 1400 hrs I can talk to you on 20 meters if you want to let me know and I will give you the Freq's I use

hi

yes i got hold of kh6ty and he has sent me a schematic of the interface. all the kits have been sold but i should have no problem in getting the parts. i probably already have most of them.

i am not at present on 20 but i have a pcb to build the bitx20 when i have the time.

currently i am only on 40m mainly cw with some ssb the radio was built from a kit.

thanks for your help

oh man, I just need to weigh into the thread...

I bought a RigBlaster, quality piece of equipment and if you are not a builder, I would highly recommend the RigBlaster...

 

HOWEVER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Radio to Computer is too damned easy! You can do it with a stereo miniplug to stereo miniplug cable and an old mic cable...

Connection DOES NOT REQUIRE – let me repeat that, DOES NOT REQUIRE!!!!!! isolation transformers. YES, isolation is good, but NOT REQUIRED!

 

Get reports on a couple contacts, if no one complains, then ignore the isolation transformers.

 

PTT DOES NOT REQUIRE, again, DOES NOT REQUIRE and optoisolator, all you need a GP NPN transisistor. ANY general purpose NPN will work. 2N2222, MPSA12, ECG123, whatever you got in the junk box. Since you are switching DC, I would recommend a resistor (1k to maybe 10k) in the base lead, just to keep the transistor from falsing.
Emitter to ground, collector to the PTT, base to the RTS/CTS on the RS232 port. Maybe you would consider a 1N4148/1N914 across the C/E  to keep transients from eating the transistor.

 

there must be 500 different web sites with rig/computer interface schematics...

hi

thanks bob for the info

i have been sent a cct with isolation transformers but i will try as you say without.
