Decreased bandwidth and increased interference from GSM networks has led to novel developments in the use of EISCAT for interplanetary scintillation (IPS) studies. The main science found from these studies is obtained through the cross-correlation of signals from antennas having the longest baseline. With 1.4GHz receivers now installed at the remote sites, and the necessity for their use at Sodankyla in particular, the cross-correlation of different observing frequencies is required. This has allowed the use of the EISCAT Svalbard Radar for IPS, increaseing the available baselines further. Increasing the sampled bandwidth is highly desirable to raise the sensitivity of IPS observations. Methods of achieving this, and the results of trials, are discussed.
