Take a look at the new pskmail_puppy live CD, now featuring full PSK250 support. It is a progam suite including fldigi, flarq, pskmail server and client, with embedded linux. http://sharon.esrac.ele.tue.nl/pub/linux/ham/pskmail/puppy Now also as application running under windows:

Rick, Welcome to the world of QRO. You didn't mention your antenna system or band. Common problems guys have: 1) open wire line with goofy unbalanced antenna attached. 2) poor grounding of the rig. (A fat short ground connecting amp and rig needed.) Corroded connections at the ground stake.

I have tried MultiPSK on packet and it is interesting, works well but is only a terminal. I once comented that converting MultiPSK into a full fledged packet mailbox was too much, considering all the other things it does well. I have not tried, but maybe with TCP/IP it could be done...using

Antenna that gives me the main problem is an inverted vee dipole with apex at about 35 feet and ends at about 15 feet high. I have a Butternut vertical located about 150 out from the house that does not seem to cause any problems, but for close in ( 200 miles) the dipole is indispensable. It

Rick, Every wire under the influence of your radiating antenna can be a feedback pickup path. Try to minimize currents, ferrites are your best friends. Use only capacitors in shunt to ground only after a choke to minimize currents. All the homebrew equipment I have built has an RF filter

Hi All: I hve had same problems,, and everything here is by the book.. single point ground antennas 1.1:1 etc etc etc RF only occured on 20 and 40 ( but entire band..) to solve problem I bought 2 T-4 un-un balums, problem is gone running al811h about 800 pep and mostly around 220 wtts digital

Rick, Your no ground situation + high power is a recipe for RF problems. Try some 1/4 wave counterpoises connected to the rig ground. You can have multiple ones for different bands connected simultaneously. People who live on second and third floors have the same problem with long ground

Worked WB8NUT and N2JR on 20M today, under pretty poor conditions. N2JR was just at my noise level and ALE400 copied as well as MFSK under these conditions. Was able to do a connect and chat , as well as upload mail to the mailbox. Very impressive and would be interested in trying it on
